Abstract
A single-element antenna is usually unable to meet the communication requirements of the wireless system, and the main solution is to use array antenna. The desire to reduce weight and cost of array antenna gave rise to sparse array. A linearly polarized sparse array antenna with ultra-wideband wide-angle scanning characteristics based on genetic algorithm (GA) is developed in this paper. The antenna array consists of 40 units, which is arranged by rectangular array with side length of 300 mm. Compared to the conventional periodic array, the proposed sparse array has reduced about 190 antenna elements. The sparse array can achieve S11 < -10 dB in the ultra-wideband of 3–12 GHz (120%). Experimental results for proposed antenna exhibit azimuth scanning angle of ±45°, pitching scanning angle of ±30°.
