- Abstract
- A Fabry-Pérot (FP) cavity antenna with a partially reflecting surface (PRS), whose lateral openings are blocked with metallic side walls, is proposed to enhance a gain and to obtain a wide beam width. A new design and analysis method is proposed to more accurately predict resonant frequency of the cavity. The effects of the cavity size on the performance of the antenna are also investigated. Consequently, an enhanced antenna gain and a sectoral beam width are achievable, which are all necessary for base station applications. In addition, total antenna efficiency higher than 90% and back radiation lower than -30dB are also obtainable. The good agreement between the measured and predicted results verifies that the proposed method is useful to design the cavity antenna with a high-gain and a sectoral radiation pattern.
