Abstract

A novel compact monopole antenna with triple-band operation is proposed in this paper. The proposed antenna, fed by a 50-Ω microstrip line, consists of an inverted-L-shaped microstrip feed line loaded with a parasitic strip and a protrudent mirrored quasi-F-shaped strip on the ground plane, with a compact overall size of 20×25 mm². The protrudent mirrored quasi-F-shaped strip is aimed to excite a resonant mode at 2.4 GHz. Meanwhile, with the introduction of the parasitic strip to the inverted-L shaped strip, two adjacent resonant frequencies at 5.2/5.8 GHz are obtained. The numerical and experimental results exhibit the designed antenna operates over triple frequency ranges, satisfying the standards of wireless local area networks (WLAN) both in IEEE 802.11 b/a/g at 2.4-GHz, 5.2-GHz, and 5.8-GHz. Besides, the antenna is fabricated and measured, and the simulation and measurement results of the return loss, radiation patterns and peak antenna gains are studied showing that the presented antenna is in good performance.
