A new center-fed circular patch antenna with two coupled annular rings is presented. When the two annular rings are coupled properly, a wide band from 5.45 GHz to 7.16 GHz is achieved with a monopole-like radiation pattern. Measured results show that the antenna with a low profile of 0.027 wavelengths (at 5.45 GHz) has a bandwidth of 27.1% and a measured maximum gain of 6 dBi. The radiation pattern is omnidirectional and remains relatively stable within the operating band.

Circular Patch Antenna

Inefficient utilization of licensed spectrum bands and overcrowding of unlicensed bands are caused due to the spectrum shortage and growing demand for wireless communication. The wireless spectrum is burdened due to the host centric traditional approaches for data detection and recovery in the IP-based networks that. The service or data is retrieved from the service provider through a new routing path every time the mobile service requester initiates a request. The vacant licensed channels are utilized appropriately enabling opportunistic and efficient band usage of the spectrum using Cognitive Radio (CR) technology. Wireless communication with low cost, compact antenna element, high gain, wideband and low profile can be performed using patch antenna. Patch is a significant aspect of antenna design. The antenna design parameters are understood by varying the patch. A good return loss can be achieved by enhancing the radiation pattern on changing the patch dimensions. High Frequency Structure Simulator (HFSS) is used for simulation and analysis of the circular patch antenna. The return loss, radiation efficiency, Voltage Standing Wave Ratio (VSWR) and radiation pattern of the antenna are analyzed.
