Abstract
A design of compact filtering antenna which is suitable for modern wireless communication is proposed in this paper. This project is based on the integration of a microstrip monopole patch antenna and a bandpass filter, which has two dual-mode four-sided open-loop resonant circuits and a single feed line. This design involves a couple of square open-loop resonators, which can create a pair of transmission by zeros, and in this method significantly boost the design's selectivity. As a confirmation of the hypothesis, For WiMAX applications, a filtering antenna technique has been explored, which operates in the 5.8 GHz range. by using CST Microwave Studio Suite simulator software Technology. The low-cost FR-4 substrate has been used to fabricate the filtering antenna prototype. According to the filter synthesis approach. In addition to radiating, the monopole patch antenna serves as a final resonator. This design shows good agreement between measured results and simulation results.
