Abstract

A U-slot loaded single-layer compact shorted-patch antenna is presented for wireless communications in the 5.8 GHz band. The size of the prototyped antenna is only 30 mm × 30 mm, which is very small compared to single-layer antennas for the same frequency band. The measured −10 dB reflection coefficient bandwidth of the antenna is 140 MHz (5.67–5.81 GHz). The peak measured boresight gain and directivity of the antenna are 7.4 and 8 dBi, respectively, and their variation within the band is less than 1 dB. The measured 3-dB beamwidths of the antenna at 5.8 GHz are 79° and 69° in the E-plane and H-plane, respectively. An easy way to shift the antenna resonance frequency is also investigated.
