Horseshoe‐shaped antenna for dual‐band WLAN communications with multi‐L slots

In this study, a novel horseshoe-shaped antenna with multi-L slots for 2.4/5-GHz wireless local area network (WLAN) operations is designed and fabricated. To obtain sufficient bandwidth when return loss (RL) < −10dB, multi-L slots are inserted (2.4 GHz) in the patch and a coaxial probe source is used. The measured result of the fabricated antenna is a 10.6% bandwidth from 2.38 to 2.51 GHz and a 28.4% bandwidth from 5.10 to 5.88 GHz (RL < −10dB), the gain 2.04–2.58 dBi. And a good radiation pattern is achieved over the WLAN band (2.4–2.484 GHz and 5.15–5.825 GHz) range. © 2008 Wiley Periodicals, Inc.
