Partially Excited Antenna Array for Near-Field Patterned Focusing

Progress In Electromagnetics Research Letters, Vol. 105, 149-154, 2022
Abstract
In this letter, a near-field focusing method for generating patterned focusing is studied. A partially excited planar array antenna is proposed for patterned focusing, which effectively suppresses the side lobes of the focusing pattern. The phase of the array antenna is adjusted by a digital phase shifter. A prototype was made and tested to verify the effectiveness of the method. Both the full planar array and the partially excited array realize the ``.'' pattern, and the partially excited array effectively reduces the side lobes. The experimental results show that the method can achieve focusing in any area. This study can provide a reference for wireless energy transfer and microwave hyperthermia.
