【Abstract】 This paper proposes a beam scanning antenna array operating in the S-band.The antenna units conduct a cross dipole design and use balun feeding,with a wide frequency band covering the 2.4～3.7 GHz frequency band(relative bandwidth 43%).The proposed 8*8 RIS antenna array is based on a designed 7-speed switch type phase shifter that can achieve horizontal plane scanning.The highest gain of the array is 22.66 dB,and the phase shifter loss is low(1.95～2.75 dB).The antenna array has a wide operating ±60° bandwidth,providing important support for the implementation and application of future wireless communication systems.更多还原
