Abstract

Circularly polarized antennas based on a new principle using a double balanced multiplier are proposed to achieve wideband and its scene switching function. The double balanced multiplier is formed by connecting four diodes in a star configuration. 90° phase difference between two orthogonal modes on the patch is realized 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, a parasitic patch is stacked on the driven patch in order to improve for performances.
