摘要：
A square slotted patch antenna for far-field wireless power transfer applications is presented. The antenna has compact size equal to 0.416 x 0.236 x 0.013 lambda which can be fit into most of the devices. It exhibits a total of 780 MHz of -10 dB impedance bandwidth in S-band with good directional characteristics. A maximum of 1.24 dB gain is observed with 1.025 dB at 2.45 GHz. A prototype of the antenna is fabricated and tested for S-band with good agreement between measured and simulated results. A computed study for far field WPT based on Friis transmission equation is presented for double ridged guide and parabolic profile horn as transmitting antennas.
