基于微机械工艺的60GHz波束扫描天线阵
Surface micro-machined beam-steering antenna array for 60 GHz radios
摘要
Abstract
A beam-steering antenna array based on surface micro-machined process was proposed for 60GHz high data rate wireless communication.The air-filled coaxial structure based surface micro-machined process provides low loss rectangular micro-coaxial transmission line and feeding network.The insertion loss of designed transmission line is less than O.18dB for both measured and simulated results.Simulated and measured results agree well.The size of beam-steering antenna array is 17.5 × 14.5 × 0.42 mm3 and bandwidth is around 10 GHz (55 ～ 65 GHz) under the condition of voltage standing wave ratio (VSWR) less than 2,which covers full frequency band standard.The steering beam directions are-± 35 ° with 11.8dBi and ± 11 ° with 12.1 dBi at 60 GHz,respectively.关键词
