Abstract
This paper introduces an investigation of two-probe excited circular ring antenna with square reflector. The purpose of this investigation is to design a diversity unidirectional antenna that is operated at the center frequency of 5.5 GHz to cover the frequency range from 5.2 to 5.8 GHz following IEEE 802.11a standard. The Computer Simulation Technology (CST) Microwave Studio is used as the simulation tool for investigating the antenna characteristics such as the return loss, the isolation between two-probes, the radiation pattern and the gain. The simulated results of the return loss, the isolation between two-probes and the radiation pattern are presented. The antenna has a unidirectional pattern with maximum gain of 8.34 dBi. Moreover, the antenna provides a unidirectional pattern with front-to-back ratio better than 20 dB and the isolation between the two-probes better than 20 dB. The proposed antenna is useful for wireless local area network (WLAN) communication systems. © 2011 IEEE.
