摘要
本文提出了一种应用于卫星通信系统的高增益,宽扫描角度的毫米波双频共口径波束扫描阵列天线。该阵列天线由八个连续横向切向节(CTS,Continuous Transverse Stub)辐射枝节,平行板波导(PPW,Parallel Plate Waveguide)功分馈电网络以及一种高性能双工器组成。基于CTS技术来设计全并馈的宽频带,高增益辐射结构;一种高性能双工器用于支持阵列天线双频共口径工作。由HFSS仿真结果表明,在20GHz和30GHz时天线最大增益分别超过25.2dBi和28.4dBi,并且在增益掉落3dBi内,该天线在20GHz和30GHz均能实现H面±40°的宽角度扫描。
This paper proposes a millimeter wave dual frequency common aperture beam scanning ar⁃ray antenna with high gain and wide scanning angle for satellite communication systems.The array antenna consists of eight continuous transverse tangential(CTS,Continuous Transverse Stub)radia⁃tion branches,a parallel plate waveguide(PPW,Parallel Plate Waveguide)power division feed net⁃work and a high-performance duplexer.Based on CTS technology,a fully parallel fed broadband,high gain radiation structure is designed.A high-performance duplexer is used to support dual frequency and common aperture operation of array antennas.The HFSS simulation results show that the maxi⁃mum antenna gain exceeds 25.2dBi and 28.4 dBi at 20 GHz and 30 GHz,respectively,and within a gain drop of 3 dBi,the antenna can achieve a wide angle scan of±40°on the H-plane at both 20GHz and 30 GHz.
