| Abstract: | A compact size microstrip line fed patch antenna used for WLAN operating at 5-GHz is proposed. The antenna consists of with horizontal "H shapped" patch on the top side, and the I slot patch with two cuts on the bottom side. The antenna is printed on a single layer substrate with a dielectric constant of 2.65 and the overall size is 15 mm×12 mm×1 mm. The simulated and measured results show good dual frequency selection, with impedance bandwidth (return loss -10 dB definition) of 210 MHz (5.17~5.38 GHz) and 318 MHz (5.68~6.02 GHz), with the gains of 1.75 dBi and 2.32 dBi, respectively. The radiation patterns of the dual frequency antenna are omnidirectional. |
