In this example a quarter wavelength open line is used where the following formula applies: WebAntenna Factor is a sensitive calibration parameter commonly used for field strength measurement. The calculator depends on an assumption that the current is uniform around the loop. It is most accurate for small loop perimeter, accuracy suffers for perimeter>0.1λ, but is usable up to about 0.3λ. The calculator assumes that the ratio E/H is ...

WebAntennas to rfPIC™ Devices.” Small loop antennas have an inherently high Q that must be reduced to simplify manufacturing. With the Q under 20, standard tolerance parts can be used while still eliminating the tuning step from manufacturing. The Q is reduced by putting a resistor in parallel with the antenna.
