摘要
提出了一种新型的微带-波导转换器,利用锥形天线实现其传输的超宽带和端射特性.将单片微波集成电路(MMIC)兼容的天线插入到矩形波导的E平面中,可以实现TE10主导模式传输.采用这种新的天线耦合方式,可以实现紧凑的结构设计和低成本的制造,而不需要多层衬底或侧壁开槽的波导结构.研究表明:在机械对准情况下,设计的超宽带(Ultra-Wide-Band)天线耦合的微带转波导连接器在6～50 GHz频带内,回波损耗优于-10 d B,电压驻波比(VSWR)小于1.22.
A novel device of microstrip-to-waveguide transition is proposed,which utilizes a tramped antenna to achieve its transmission qualities of ultra-wide band and end-fire radiation. This Monolithic-Microwave IntegratedCircuit( MMIC)-compatible antenna is inserted in the E-plane of the rectangular waveguide to launch the TE10 dominant mode. With this new excitation scheme,compact design and low-cost manufacturing are obtained without the need of multi-layer substrates or waveguide sidewall slits. The study shows that,under mechanical alignment,the designed microstrip-to-waveguide connector coupled with Ultra-Wide-Band( UWB) antenna has obtained a return loss better than-10 dB and a Voltage Standing Wave Ratio( VSWR) less than 1.22 within the band( 6-50 GHz).
