针对VLBI（Very Long Baseline Interferometry）多波段接收机系统的相位校准系统，设计并制作了一种宽带双脊角锥喇叭。喇叭的工作频带覆盖22和129 GHz。双脊波导结构已被用于超宽带应用。测量的回波损耗优于9.4 dB和辐射模式的测量结果进行了比较，从22到110 GHz的模拟。
A wideband double-ridged pyramidal horn has been designed and fabricated for a phase calibration system, which is being developed for VLBI (Very Long Baseline Interferometry) multi-band receiver system. The operating frequency band of the horn covers across 22 and 129 GHz. Double-ridged waveguide structure has been employed for the ultra-wideband application. Measured return loss is better than 9.4 dB and measurements of radiation patterns are compared with simulations from 22 to 110 GHz.
