The proposed antenna is designed, fabricated and measured. Experimental results are in good agreement with simulations. In the band of 2.27-2.58 GHz, the return loss is better than 10 dB and the gain better than 6 dBi.enYagi-Uda antennaparasitic resonatorenhanced bandwidthArticleDepartment of Electrical and Computer Engineering
