Abstract
In this paper, advanced dual patch ring antenna for multi-band applications is proposed. The simulated results show that the proposed antenna operates at six resonant frequencies, which covers different wireless communication applications. The single antenna consists of a quasi-modified circular radiating patch with a partial ground plane and two parasitic elements (open-loop-ring resonators) to serve as coupling-bridges. A stepped cut at the partial ground plane is used, to achieve the multi-band features. The proposed antenna is simulated and optimized using High-Frequency Simulation System (HFSS). The dual patch ring antenna topology possesses an area of 55 × 53 mm2. The measured results have been done for the single antenna design which has impedance bandwidths for 10 dB return loss and meet the requirements of worldwide interoperability for microwave access (Wi-MAX) and RADAR applications. An Acceptable agreement is obtained between measurement and simulation results. Experimental results show that the antenna is successfully simulated and measured.
