Radial Line Slot Array Antenna for 5.8-GHz-Band Beam-Type Wireless Power Transmission
2020
This paper presents beam-type wireless power transmission by two radial line slot array antennas (RLSA). Using electrically large antennas and their near-field region enables high-efficiency wireless power transmission. A uniformly excited RLSA is designed at 5.8-GHz-band, one of the industry science and medical (ISM) band. The two designed RLSAs are placed vis-a-vis and transmission are analyzed. At the distance of 28 cm, 67% transmission is confirmed whereas the rest is spill-over, material loss, and reflection loss.
