A Wide Bandwidth Folded V-Shaped Patch Antenna with Stable High Gain and Low Cross-Polarization Characteristics

A wide bandwidth folded V-shaped patch antenna with high gain and low cross polarization is presented. The proposed antenna is composed of a folded V-shaped patch, an H-shaped coupling slot cut in the ground plane and a feed line with a stub printed on the bottom layer of the grounded substrate. By folding the V-shaped metallic patch, the proposed antenna can achieve a low profile structure and good performance in radiation patterns. The antenna element and the antenna array operating at 2 GHz were fabricated and tested. The prototypes with the single element can achieve a −10 dB return loss bandwidth of 28.5% (1.65 to 2.2 GHz) and a stable gain of 8.6 dBi, while the 1 × 2 array exhibits a bandwidth of 34.1% (1.58 to 2.23 GHz) and a stable gain of 11.5 dBi.
