ABSTRACT:
A small loop antenna employs circuits for increasing the power output and bandwidth of such antennas by employing coaxial cable or wide antenna elements on which the coaxial cable may be mounted or use microstrip, both for the purpose of reducing the inductance and resistance of the antenna structure in a fixed ratio so that the reduced terminating resistance increases the level of signal output. This method applies to both receiving and transmitting antennas for cases where the terminating resistance is much larger than the radiation resistance plus the antenna and tuner loss resistances.
