一种毫米波宽带高增益低交叉极化背腔贴片阵列天线
A Millimeter-Wave Wideband SIW Cavity-Backed Patch Array Antenna with High Gain and Low Cross Polarization
摘要
Abstract
A millimeter-wave wideband substrate integrated waveguide(SIW)cavity-backed patch array antenna with high gain and low cross polarization is proposed.Firstly,a patch antenna element is designed on an SIW cavity.By introducing an interrupted slot and two metal vias,the element is excited through a coupling slot beneath the SIW cavity.Secondly,to further reduce the cross-polarization level and facilitate the array layout,a four-port SIW feeding cavity is introduced,thereby forming a 2×2 sub-array.Based on this sub-array,an 8×8 array is realized by integrating a sixteen-port wideband feeding network.Finally,a prototype is fabricated and tested.The measured results show that the simulated and measured reflection coefficients are 38.1%and 36.3%,respectively.The simulated and measured peak gains reach 27.5 dBi and 26.7 dBi,respectively,while the simulated and measured cross-polarization levels are below-60.3 dB and-41.2 dB,respectively,indicating excellent radiation performance.关键词
