Antenna Definitions and Useful Formulas VSWR - Voltage Standing Wave Ratio. VSWR is a unitless ratio that describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. VSWR is easily derived from Return Loss. VSWR = 10 Return Loss 20 + 1 Return Loss 20 −1 Return Loss = −20 log10 VSWR −1 VSWR + 1 Gdb = 10 log10(G) GdBd = GdBi −2.51dB VSWR −1 VSWR + 1 TRE = η 1 − VSWR −1 VSWR + 1 □ /4 Return Loss - Return loss represents the loss in power at the antenna due to reflected signals, measured in decibels. A lower return loss value indicates better antenna performance at a given frequency. Return Loss is easily derived from VSWR. VSWR = 10 Return Loss 20 + 1 Return Loss 20 −1 Return Loss = −20 log10 VSWR −1 VSWR + 1 Gdb = 10 log10(G) GdBd = GdBi −2.51dB VSWR −1 VSWR + 1 TRE = η 1 − VSWR −1 VSWR + 1 □ /4 Efficiency (η) - The total power radiated from an antenna divided by the input power at the feed point of the antenna as a percentage. Total Radiated Efficiency - (TRE) The total efficiency of an antenna solution comprising the radiation efficiency of the antenna and the transmitted (forward) efficiency from the transmitter. VSWR = 10 Return Loss 20 + 1 Return Loss 20 −1 Return Loss = −20 log10 VSWR −1 VSWR + 1 Gdb = 10 log10(G) GdBd = GdBi −2.51dB VSWR −1 VSWR + 1 TRE = η 1 − VSWR −1 VSWR + 1 □ /4 Gain - The ratio of an antenna’s efficiency in a given direction (G) to the power produced by a theoretical lossless (100% efficient) isotropic antenna. The gain of an antenna is almost always expressed in decibels. VSWR = 10 Return Loss 20 + 1 Return Loss 20 −1 Return Loss = −20 log10 VSWR −1 VSWR + 1 Gdb = 10 log10(G) GdBd = GdBi −2.51dB VSWR −1 VSWR + 1 TRE = η 1 − VSWR −1 VSWR + 1 □ /4 Peak Gain - The highest antenna gain across all directions for a given frequency range. A directional antenna will have a very high peak gain compared to average gain. Average Gain - The average gain across all directions for a given frequency range. Maximum Power - The maximum signal power which may be applied to an antenna feed point, typically measured in watts (W). Reflected Power - A portion of the forward power reflected back toward the amplifier due to a mismatch at the antenna port. VSWR = 10 Return Loss 20 + 1 Return Loss 20 −1 Return Loss = −20 log10 VSWR −1 VSWR + 1 Gdb = 10 log10(G) GdBd = GdBi −2.51dB VSWR −1 VSWR + 1 TRE = η 1 − VSWR −1 VSWR + 1 □ /4 decibel (dB) - A logarithmic unit of measure of the power of an electrical signal. decibel isotropic (dBi) - A comparative measure in decibels between an antenna under test and an isotropic radiator. decibel relative to a dipole (dBd) - A comparative measure in decibels between an antenna under test and an ideal half-wave dipole. Dipole - An ideal dipole comprises a straight electrical conductor measuring 1/2 wavelength from end to end connected at the center to a feed point for the radio. Isotropic Radiator - A theoretical antenna which radiates energy equally in all directions as a perfect sphere. Omnidirectional - Term describing an antenna radiation pattern that is uniform in all directions. An isotropic antenna is the theoretical perfect omnidirectional antenna. An ideal dipole antenna has a donut- shaped radiation pattern and other practical antenna implementations will have less perfect but generally omnidirectional radiation patterns which are typically plotted on three axes.
