Abstract | This paper presents a design of a compact microstrip patch antenna with the ability of controlling the number of bands and the operating frequencies independently. The antenna comprises a main patch and four sub-patches fed by a 50 ¿ microstrip line. It is designed to generate up to five separate modes to cover the frequency range from 900 MHz to 3 GHz for the operation of wireless devices supporting multiple standards including Global System for Mobile communication (GSM900, 880-960 MHz), Digital Communication System (DCS1800, 1710-1880 MHz), Universal Mobile Telecommunication System (UMTS, 1920-2170 MHz), Wireless Local Area Network (WLAN, 2400-2483.5 MHz) and low band Worldwide Interoperability for Microwave Access (WIMAX, 2.5 to 2.8 GHz) The design verified through both numerical simulation and measurement of an experimental prototype. |
