Abstract This article proposes a novel patch antenna using a polarization control module to achieve a broad matching bandwidth and broad 3‐dB gain bandwidth over the entire axial ratio (AR) range. The proposed antenna consists of a shorted radiating patch, an L‐shaped indirect feed, and a polarization control module that can adjust AR properties over the entire AR range (−1 < AR < 1) with a broad 3‐dB gain bandwidth for use in various practical applications. The measured results demonstrate that the proposed antenna can adjust the polarization properties with a broadband matching bandwidth of more than 27% (370 MHz) and a broad 3‐dB gain bandwidth greater than 26% (351 MHz) over the entire AR range.
