Abstract

This paper proposes the configuration of a novel wideband patch antenna system suitable especially for indoor mobile communication applications. This configuration consists of an elevated patch antenna, which has different feed structure from classical patch antenna feed configurations that the antenna is fed by an inverted L-shape structure. The antenna structure is designed, simulated and manufactured in order to be used in mobile communication applications when used in pairs that its operation bandwidth spans 1900-2700 MHz covering Bluetooth, Wireless Local Area Networks (WLAN) and Universal Mobile Telecommunications System (UMTS) bands. Simulation and measurement results show that the antenna has wide beamwidth, low return loss and cross polarization; but, comparably higher back lobe level making the antenna more suitable for indoor applications. However, the antenna can be modified to be used in outdoor applications by increasing the ground plane size, which results in lower back lobe levels.
