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." It is sometimes expressed as a percentage (less than 100), and is frequency dependent.

dBi - antenna gain (‘G’) expressed in dBi shows a value in decibels by which the antenna gain is higher than that of a hypothetical isotropic antenna assuming that both antennas are fed with the same power. Small Magnetic Loop Antenna Calculator ver. 1.22a by Steve Yates AA5TB aa5tb@yahoo.com Updated April 28, 2009 Input the following parameters: Design Frequency = MHz Loop Diameter = feet m Small loop diameter = Conductor Diameter = inches mm Added Loss Resistance = milliohms RF Power = Watts Calculated Results: Bandwidth = kHz (-3 dB points The antenna accepts a certain amount of energy delivered to it by the transmission line (characterized by S11, VSWR, or return loss), and Antenna Efficiency characterizes the amount of energy lost ‘in’ the antenna after this. It is often expressed in terms of a percentage, or in dB. For example, an efficiency of 0.8 is 80%, or -0.97dB. 2014-10-20 · " Transmitter antenna has an active gain of +12dB " The two antennas are 124 meters away from one another " Ignore the attenuation of the coax cable ! Answer the following " The power in Watts as Receiver Y receives.

You may convert percentage (linear) to dB (logarithmic) by using the following equations: dB = 10 log(1 + X) Example X = 1% Thus, dB = 10 log(1 + 0.01) dB = 0.0432

This means that you can not convert dB dBm dBW dBV etc to dBi it is meaningless unless you know what the dB is referring to and the reference comparison makes sense. Man and machine. Machine and man. The constant struggle to outperform each other. Man has relied on machines and their efficiency for years. So, why can’t a machine be 100 percent efficient?
