Abstract
A microstrip antenna transceiver with switchable polarizations includes a substrate, a first switch element, a second switch element and an antenna module. The first switch element and the second switch element are disposed on a first surface of the substrate; the antenna module is disposed on a second surface of the substrate and includes a radiation patch including a first pattern slot, a vertical polarization feed-in point and a horizontal polarization feed-in point. The vertical polarization feed-in point and the horizontal polarization feed-in point are symmetric with respect to a symmetrical axis. Size and displacement of the first pattern slot are related to reflection phase of the first switch element and the second switch element in order to generate a right-handed polarized signal or a left-handed polarized signal.
