摘要

In this letter, we present a low-profile switchable quadripolarization diversity aperture-coupled patch antenna. The proposed antenna can provide four polarization states by controlling the dc bias voltage of four p-i-n diodes in the feeding network. The experimental results validate the novel antenna provides polarization diversity features for wireless local area networks (WLANs) and multiple-input-multiple-output (MIMO) systems.
