A high-gain printed antenna array with directional pattern for WiFi application

In this paper, a 2×2 antenna array operating at WiFi band has been proposed. The antenna elements are fed with opposite phase to enhance antenna gain. A power divider with phase shift has been designed to feed the antenna array. The antenna works at frequencies about 5.8 GHz, with −10dB bandwidth of 5.64-6.08 GHz. The simulated maximum gain of the array reaches to 11.46 dB.
