text: A second unit used to measure gain is the ratio of the power radiated by the antenna to the power radiated by a half-wave dipole antenna I dipole {\displaystyle \scriptstyle I_{\text{dipole}}} ; these units are called "decibels-dipole" (dBd)
text: Radiation efficiency is defined by IEEE Std 145-1993 "Standard Definitions of Terms for Antennas" as "The ratio of the total power radiated by an antenna to the net power accepted by the antenna from the connected transmitter.
text: An antenna's efficiency is a measure of how much power is radiated by the antenna relative to the antenna input power.
text: Specifically, the antenna gain, or power gain of an antenna is defined as the ratio of the intensity (power per unit surface) radiated by the antenna in the direction of its maximum output, at an arbitrary distance, divided by the intensity radiated at the same distance by a hypothetical isotropic antenna .
text: It is important to emphasize that in spite of the names, ERP and EIRP do not measure transmitter power, or total power radiated by the antenna, they are just a measure of signal strength along the main lobe.
text: ERP and EIRP are always greater than the actual total power radiated by the antenna.
text: This is integrated over a sphere enclosing the antenna to give the total power P R {\displaystyle P_{\text{R}}} radiated by the antenna.
text: In addition to reducing the power radiated by the antenna, the mismatch can distort the signal, and in high power transmitters may overheat the transmitter.
text: Without an ATU, in addition to reducing the power radiated by the antenna, the reflected current can overheat transformer cores and cause signal distortion.
text: Antenna directivity is the ratio of maximum radiation intensity (power per unit surface) radiated by the antenna in the maximum direction divided by the intensity radiated by a hypothetical isotropic antenna radiating the same total power as that antenna.
text: Specifically, the Gain or Power gain of an antenna is defined as the ratio of the intensity (power per unit surface) radiated by the antenna in a given direction at an arbitrary distance divided by the intensity radiated at the same distance by an hypothetical isotropic antenna:
text: Thus the power radiated by the antenna is 8685 times more concentrated along the boresight direction than for an isotropic antenna, which by definition has a gain of 1 (0 dB).
text: A second unit used to measure gain is the ratio of the power radiated by the antenna to the power radiated by a half-wave dipole antenna I dipole {\displaystyle \scriptstyle I_{\text{dipole}}} ; these units are called "decibels-dipole" (dBd)
text: Total Radiated Power (TRP) is a measure of how much power is radiated by an antenna when the antenna is connected to an actual radio (or transmitter).
