Abstract

Circularly polarized antennas based on a new principle using a double balanced multiplier are proposed to achieve small and wideband antennas. The double balanced multiplier is formed by connecting four diodes in a star configuration and it realizes 90° phase difference between two orthogonal modes by controlling the bias voltage. Therefore, circular polarizations are obtained. RHCP and LHCP can be switched by the polarity of the bias voltage. In this paper, nonlinear characteristics of DBM integrated circularly polarized antenna is experimentally investigated.
