Abstract
In this paper, the novel patch antenna for polarization diversity using switching element is presented. The proposed antenna consists of the square patch with a pair of truncated corners and a microstrip-feed line with power divider. A switching microstrip-line feed works at schottky diode ON / OFF that is placed at $\lambda$/4 point from branch-off point of power divider. Polarization diversity has two types(LHCP. RHCP) as switching the schottky diodes. The measured 3 ㏈ axial ratio bandwidth for switching operation is about 2 %.
