Efficiency of Differential Receiving Antenna Interfaced to a Three-Port Network

Abstract

Differential antennas feeding networks are encountered in a wide range of applications, but the performance is usually analyzed with the simplest network, which is an impedance. This work generalizes this analysis to any three ports network containing passive and/or active components, which is usually described by a set of S parameters. This approach may be used to optimize the overall design of both antenna and network.
