A Novel Wideband TE21 Mode Coupler for Monopluse Feed

Yan-Bo Meng, Rui He, Zehong Yan

Open publisher page 2 citations

Abstract

In this letter, a novel coupler for TE21 mode of circular waveguide is introduced. The novel coupler is used to track satellite signal which works at downlink frequency band of satellite communication. The frequency relative bandwidth of the novel coupler can reach about 10%. The structure of the novel coupler is different, which reflects in the shape and distribution of coupling holes. The novel coupler is used to couple TE21 mode, which operate with the main mode to track target. Compared to traditional coupler, this novel coupler takes into account both communication performance and structure performance.
