Summary: | In this paper, a hybrid zeroth-order resonance (ZOR) patch antenna with a broad E -plane beamwidth is presented. In order to obtain the broad beamwidth of an antenna, a TM 010 (λ 0 /2) mode and a ZOR mode are combined. By dividing the incident power to two modes, the E -plane beamwidth of a TM 010 mode can simply be controlled. To generate the TM 010 mode and the ZOR mode, simultaneously, the mushroom antenna is inserted in a rectangular patch antenna with an etched rectangular hole and a single feed is employed between two radiators. The incident power to each antenna can be controlled by using the gap of a feed. Thus, the optimum incident power ratio having the broadest E -plane half power beamwidth (HPBW) is obtained. As a result, the E -plane HPBW of the proposed antenna is measured as 115° and broadened by 53%, compared with that of the conventional rectangular patch antenna. Moreover, the bandwidth and the efficiency of the antenna are measured to be 3.3% and 92%, respectively. Finally, the measured results show good agreements with the simulated ones. |
