E-shape microstrip patch antenna for wideband applications

摘要

This paper presents the design of E-shaped microstrip single patch antenna with wideband operating frequency for wireless application. The antenna design is an improvement from previous research and it is simulated using CST Microwave Studio 2009 software. Parametric study was included to determine affect of design towards the antenna performance. The performance of the designed antenna was analyzed in term of bandwidth, gain, return loss, VSWR, and radiation pattern. The design was optimized to meet the best possible result. Substrate used was C-Foam PF-2 which has a similar dielectric constant of air. The results show the wideband antenna is able to operate from 8.34 GHz to 13.86 GHz frequency band with optimum frequency at 8.73 GHz.
