N2 - This paper introduces a polarization reconfigurable aperture-fed 1×4 patch antenna array. A reconfigurable aperture structure is realized by placing RF switches on four horizontally-Aligned cross apertures of a ground plane. Four square radiating patches are excited through these apertures by the 14 microstrip feeding lines. To simplify the scheme of DC biases, four copper strips are placed inside each cross aperture. PIN diodes are connected between these strips and ground as RF switches. By controlling these diodes with two DC biases, ± 45 linear polarizations can be switched. The patch array can achieve the maximum broadside gain of 13.5 dBi and the-10 dB impedance bandwidth of 9.3% from 2.25 to 2.47 GHz. The proposed antenna has a stable gain and low cross polarization level across the entire operating bandwidth.
