L波段紧凑型TEM-TE11模式转换器
Compact L band TEM-TE11 mode converter
摘要
Abstract
A compact TEM-TEn mode converter suitable for narrow band high power microwave system was developed. The coaxial waveguide is divided into several sectorial waveguides with different phase propagation constants, and the waveguides with relatively large phase propagation constants are transversely folded to shorten their axial lengths. When the microwaves in different sectorial waveguides have a phase shift of 180 degrees at the end of the mode converter, they compose a coaxial TEu mode. A mode converter is designed for the 1. 31 GHz L-band magnetically insulated transmission line oscillator (MILO) system. The conversion efficiency of TEM-TEn mode at center frequency is 95%. In the frequency range of 1. 23-1. 40 GHz, the conversion efficiency exceeds 90% , with a corresponding bandwidth of 13%. The directional radiation performance of the mode converter connected to an L-band MILO tube is tested. The experimental result reveals that the mode converter works well.关键词
