A Compact UWB Circular Patch Antenna for X-Band and WLAN Applications

Abstract

A composite circular microstrip patch antenna (MPA) with aperture opening for UWB architecture is intended. Double recurrence circular patch configuration along aperture opening slot fed with a microstrip line are planned to achieve coupled recurrence task. The design involves the circular patch and space resonator. The moderation in the radio wire design for the auxiliary band is realized by a U –shaped resonator. The U-shaped aperture is employed in the ground plane to realize dual frequency operation. By modifying structure parameters, the patch works at the Xband (8.69 GHz) for satellite communications and parasitic - opening works at UNII band (5.15 GHz) for WLAN applications, the two resonators are transmitting with two diverse radiation designs. The designed antenna is small in size, less weight, reduced in cost and satisfactory confinement. The antenna analysis shows the desired return loss (<-10 dB), improved radiation pattern over working bands. To analyze the attainment of receiving wire, practical specifications, for example, reflection coefficient, data transmission and radiation design are resolved by the recreation of the designed model with HFSS. Designed antenna configuration is appropriate for ultra-wideband applications.
