Abstract:

The methodology for designing a TM01-mode coupler is presented which operates in two removed bands. The coupler consists of two parts: a coupler main body and a synthesizing network. The former separates the two bands and the latter works in the lower band to separate the transmission and reception of circular polarization from linear polarization tracking. The paper covers the design principles as well as a Ka-band example with good experimental performance.

Key words: multi-mode coupler, circular polarization, linear polarization, polarization tracking
