Description
Summary:A square slotted patch antenna for far-field wireless power transfer applications is presented. The antenna has compact size equal to 0.416 \times 0.236 \times 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.
