The Voltage Standing Wave Ratio (VSWR) is a measurement of how well an antenna is matched to a source impedance, typically 50-ohms. It is calculated by measuring the voltage wave that is headed toward the load versus the voltage wave that is reflected back from the load. A perfect match has a VSWR of 1:1. The higher the first number, the worse the match, and the more inefficient the system. Since a perfect match cannot ever be obtained, some benchmark for performance needs to be set. In the case of antenna VSWR, this is usually 2:1. At this point, 88.9% of the energy sent to the antenna by the transmitter is radiated into free space and 11.1% is either reflected back into the source or lost as heat on the structure of the antenna. In the other direction, 88.9% of the energy recovered by the antenna is transferred into the receiver. As a side note, since the ":1" is always implied, many data sheets will remove it and just display the first number. How to Read a VSWR Graph VSWR is usually displayed graphically versus frequency. The lowest point on the graph is the antenna's operational center frequency. In most cases, this is different than the designed center frequency due to fabrication tolerances. The VSWR at that point denotes how close to 50-ohms the antenna gets. Linx specifies the recommended bandwidth as the range where the typical antenna VSWR is less than 2:1. -2- ANT-8/9-VDP-2000-ccc Data Sheet Gain Plots 2400 - 2500MHz 350 340 0 5.00 350 10 340 20 0.00 330 -5.00 320 -10.00 310 310 50 -20.00 80 50 310 60 90 260 100 250 230 -40.00 280 210 230 250 110 240 120 230 140 210 140 210 160 190 170 XZ-Plane Gain 130 220 150 200 160 180 100 130 220 180 90 260 120 150 200 -50.00 270 110 240 140 80 -45.00 90 100 130 220 70 -35.00 250 120 60 -30.00 290 80 260 110 240 50 -25.00 70 -50.00 270 40 -20.00 -45.00 -50.00 30 -15.00 300 -40.00 280 20 -10.00 -30.00 -45.00 190 320 -35.00 -40.00 10 -5.00 -25.00 290 70 -35.00 270 40 0 5.00 0.00 330 -20.00 300 60 -30.00 280 340 30 -15.00 -25.00 290 350 20 -10.00 -15.00 300 10 -5.00 320 40 0 5.00 0.00 330 30 150 200 170 YZ-Plane Gain 2400MHz 160 190 180 170 2450MHz XY-Plane Gain 2500MHz 5720 - 5880MHz 350 340 0 5.00 10 350 340 20 0.00 330 -5.00 320 -10.00 310 310 50 -20.00 80 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 190 180 170 60 -30.00 70 -35.00 80 -40.00 280 80 -45.00 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 190 50 -25.00 290 70 -50.00 270 40 -20.00 -45.00 -50.00 30 -15.00 300 60 -40.00 280 -45.00 270 310 50 -35.00 -40.00 20 -10.00 -30.00 -35.00 10 -5.00 -25.00 290 70 0 5.00 0.00 320 40 -20.00 300 60 -30.00 280 340 330 30 -15.00 -25.00 290 20 -10.00 -15.00 300 350 10 -5.00 320 40 0 5.00 0.00 330 30 180 170 -50.00 270 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 190 180 170 XZ-Plane Gain YZ-Plane Gain XY-Plane Gain XZ-Plane Gain YZ-Plane Gain XY-Plane Gain -3- ANT-8/9-VDP-2000-ccc Data Sheet 5720MHz 5800MHz 5880MHz Performance in the U-NII Band XZ-Plane Gain YZ-Plane Gain XY-Plane Gain 5120 - 5720MHz 350 340 0 5.00 350 10 340 20 0.00 330 -5.00 320 -10.00 310 310 50 -20.00 80 50 310 60 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 180 170 XZ-Plane Gain 70 -40.00 280 80 -45.00 90 100 250 110 240 120 230 130 220 140 210 150 200 160 180 170 YZ-Plane Gain VSWR -50.00 270 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 190 180 170 XY-Plane Gain 1.265 Reflected Power 25% 3:1 11% 2:1 1:1 5.11GHz 60 -30.00 -35.00 80 260 190 50 -25.00 290 -50.00 270 40 -20.00 -45.00 -50.00 30 -15.00 300 70 -40.00 280 20 -10.00 -30.00 -45.00 190 320 -35.00 -40.00 10 -5.00 -25.00 290 70 -35.00 270 40 0 5.00 0.00 330 -20.00 300 60 -30.00 280 340 30 -15.00 -25.00 290 350 20 -10.00 -15.00 300 10 -5.00 320 40 0 5.00 0.00 330 30 5.425GHz -4- 0% 5.74GHz ANT-8/9-VDP-2000-ccc Data Sheet 5120MHz 5420MHz 5720MHz About Gain Plots The true measure of the effectiveness of an antenna in any given application is determined by the gain and radiation pattern measurement. For antennas gain is typically measured relative to a perfect (isotropic) radiator having the same source power as the antenna under test, the units of gain in this case will be decibels isotropic (dBi). The radiation pattern is a graphical representation of signal strength measured at fixed distance from the antenna. Gain when applied to antennas is a measure of how the antenna radiates and focuses energy into free space. Much like a flashlight focuses light from a bulb in a specific direction, antennas focus RF energy into specific directions. Gain in this sense refers to an increase in energy in one direction over others. It should also be understood that gain is not "free", gain above 0dBi in one direction means that there must be less gain in another direction. Pictorially this can be pictured as shown in the figures to the right. The orange pattern represents the radiation pattern for a perfect dipole antenna, which is shaped like a donut. The pattern for an omnidirectional antenna with gain is shown in blue. The gain antenna is able to work with a device located further from the center along the axis of the pattern, but not with devices closer to the center when they are off the axis - the donut has been squished. Gain is also related to the overall physical size of the antenna, as well as surrounding materials. As the geometry of the antenna is reduced below the effective wavelength (considered an electrically small antenna) the gain decreases. Also, the relative distance between an electrically small antenna and its associated ground impacts antenna gain.

The Voltage Standing Wave Ratio (VSWR) is a measurement of how well an antenna is matched to a source impedance, typically 50-ohms. It is calculated by measuring the voltage wave that is headed toward the load versus the voltage wave that is reflected back from the load. A perfect match has a VSWR of 1:1. The higher the first number, the worse the match, and the more inefficient the system. Since a perfect match cannot ever be obtained, some benchmark for performance needs to be set. In the case of antenna VSWR, this is usually 2:1. At this point, 88.9% of the energy sent to the antenna by the transmitter is radiated into free space and 11.1% is either reflected back into the source or lost as heat on the structure of the antenna. In the other direction, 88.9% of the energy recovered by the antenna is transferred into the receiver. As a side note, since the ":1" is always implied, many data sheets will remove it and just display the first number. How to Read a VSWR Graph VSWR is usually displayed graphically versus frequency. The lowest point on the graph is the antenna's operational center frequency. In most cases, this is different than the designed center frequency due to fabrication tolerances. The VSWR at that point denotes how close to 50-ohms the antenna gets. Linx specifies the recommended bandwidth as the range where the typical antenna VSWR is less than 2:1. -2- ANT-8/9-VDP-2000-ccc Data Sheet Gain Plots 860 - 870MHz 0 350 5.00 340 350 10 340 20 0.00 330 -5.00 320 -10.00 310 310 50 -20.00 80 50 310 60 90 260 100 250 230 -40.00 280 210 230 250 110 240 120 230 140 210 140 210 160 190 170 XZ-Plane Gain 130 220 150 200 160 180 100 130 220 180 90 260 120 150 200 -50.00 270 110 240 140 80 -45.00 90 100 130 220 70 -35.00 250 120 60 -30.00 290 80 260 110 240 50 -25.00 70 -50.00 270 40 -20.00 -45.00 -50.00 30 -15.00 300 -40.00 280 20 -10.00 -30.00 -45.00 190 320 -35.00 -40.00 10 -5.00 -25.00 290 70 -35.00 270 40 0 5.00 0.00 330 -20.00 300 60 -30.00 280 340 30 -15.00 -25.00 290 350 20 -10.00 -15.00 300 10 -5.00 320 40 0 5.00 0.00 330 30 150 200 170 YZ-Plane Gain 860MHz 160 190 180 170 870MHz XY-Plane Gain 900 - 930MHz 350 340 0 5.00 10 350 340 20 0.00 330 -5.00 320 -10.00 310 310 50 -20.00 80 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 190 180 170 60 -30.00 70 -35.00 80 -40.00 280 80 -45.00 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 190 50 -25.00 290 70 -50.00 270 40 -20.00 -45.00 -50.00 30 -15.00 300 60 -40.00 280 -45.00 270 310 50 -35.00 -40.00 20 -10.00 -30.00 -35.00 10 -5.00 -25.00 290 70 0 5.00 0.00 320 40 -20.00 300 60 -30.00 280 340 330 30 -15.00 -25.00 290 20 -10.00 -15.00 300 350 10 -5.00 320 40 0 5.00 0.00 330 30 180 170 -50.00 270 90 260 100 250 110 240 120 230 130 220 140 210 150 200 160 190 180 170 XZ-Plane Gain YZ-Plane Gain XY-Plane Gain XZ-Plane Gain YZ-Plane Gain XY-Plane Gain -3- ANT-8/9-VDP-2000-ccc Data Sheet 900MHz 920MHz 930MHz About Gain Plots The true measure of the effectiveness of an antenna in any given application is determined by the gain and radiation pattern measurement. For antennas gain is typically measured relative to a perfect (isotropic) radiator having the same source power as the antenna under test, the units of gain in this case will be decibels isotropic (dBi). The radiation pattern is a graphical representation of signal strength measured at fixed distance from the antenna. Gain when applied to antennas is a measure of how the antenna radiates and focuses energy into free space. Much like a flashlight focuses light from a bulb in a specific direction, antennas focus RF energy into specific directions. Gain in this sense refers to an increase in energy in one direction over others. It should also be understood that gain is not "free", gain above 0dBi in one direction means that there must be less gain in another direction. Pictorially this can be pictured as shown in the figures to the right. The orange pattern represents the radiation pattern for a perfect dipole antenna, which is shaped like a donut. The pattern for an omnidirectional antenna with gain is shown in blue. The gain antenna is able to work with a device located further from the center along the axis of the pattern, but not with devices closer to the center when they are off the axis - the donut has been squished. Gain is also related to the overall physical size of the antenna, as well as surrounding materials. As the geometry of the antenna is reduced below the effective wavelength (considered an electrically small antenna) the gain decreases. Also, the relative distance between an electrically small antenna and its associated ground impacts antenna gain.
