A novel stacked-patch endfire antenna

This paper presents a novel stacked patch antenna design with stable radiation and high gain characteristics. The presented antenna provides the bandwidth from 2.4 GHz to 2.483GHz. This bandwidth is realized by stacking the copper sheet. The bandwidth of the stacked antenna is narrow, but results in stable radiation patterns and high gain in the operating band, and the main gain can achieve 8.9dBi.
