摘要

设计并制作了一种用于150 GHz频段的垂直极化水平平面全向天线，该天线采用圆波导弯曲模式转换器和轴对称单反射器。选取147.8 GHz ~ 170.0 GHz频率范围作为工作频段，其中$\text{TE}_{11}$模式与$\text{TM}_{01}$模式的传输系数比小于1/3，在设计的模式变换器中，实现增益为2.2 ~ 8.8 dBi，在该频段测量频率下的角增益变化最大为4.9 dB

Vertically Polarized Omnidirectional Reflector Antenna Fed by a Circular Waveguide Bent TM01 Mode Converter for the 150 GHz Band

A vertically polarized horizontal-plane omnidirectional antenna with a circular waveguide bent $\text{TM}_{01}$ mode converter and an axisymmetric single reflector is designed and fabricated for the 150 GHz band. Determining a frequency range of 147.8 GHz to 170.0 GHz as the operational band, where the transmission coefficient ratio of the $\text{TE}_{11}$ mode to the $\text{TM}_{01}$ mode is less than 1/3 that in the designed mode converter, the realized gain is 2.2 dBi to 8.8 dBi, and the angular gain variation at the measured frequencies in the band is 4.9 dB at the maximum in the fabricated antenna
