Microstrip Antenna Transceiver

摘要

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.

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