摘要

本文介绍了三种不同的射电天文馈电喇叭天线。设计并仿真了含扼环角、锥形波纹角和指数型四脊角的进给结构。采用相同直径的圆波导来激励所有天线输入端的主导TE11模式。在q波段范围内，研究了各馈电喇叭在波束宽度、增益、交叉极化和旁瓣电平方面的性能。

Design and analysis of three Q-band Feed Horns for Radio astronomy applications

Three different feed horn antennas for radio astronomy applications are presented in this paper. Feed structures including Choked ring horn, conical corrugated horn, and exponentially shaped quad-ridged horn are designed and simulated. Circular waveguide with same diameter is used for exciting the dominant TE11 mode in the input of all proposed antennas. The performance of each feed horn regarding the beamwidth, gain, cross polarization and side lobe levels are investigated in Q-band frequency range.
