Abstract

This article describes the design, fabrication, and measurement of a novel φ-shaped dual-band antenna with a shorting pin for 5.2/5.8 GHz wireless local area network (WLAN) systems. To obtain sufficient bandwidth when return loss (RL) < -10 dB, a shorting pin is inserted in the patch and a coaxial probe source is used. The measured result of the fabricated antenna provides 211 MHz bandwidth from 5.147 to 5.358 GHz and 114 MHz bandwidth from 5.712 to 5.826 GHz (RL < -10 dB) with the gain ranging from 5.73 to 6.52 dBi. Also, a good radiation pattern is achieved within the WLAN band (5.150-5.350 GHz and 5.725-5.825 GHz) range.
