Compact Triple-Arm Multi-Band Monopole Antenna

Abstract

This paper presents a multi-band, compact, lightweight and low-cost monopole antenna suitable for applications in the wireless local area network (WLAN) and DCS1800/PCS1900 bands. The antenna has a thin substrate, small area and is fed by a microstrip line, which can be directly connected with the associated microwave circuits. The computed and measured results for 1.8, 2.4, 4.9, 5.2 and 5.8 GHz band cases are presented.
