Dual-Band Ortho-Mode Transducer with Irregularly Shaped Diaphragm

Progress In Electromagnetics Research Letters, Vol. 27, 1-8, 2011
Abstract
A compact dual-band ortho-mode transducer is presented in this paper. Two orthogonally polarized signals received by a square waveguide are separated into two orthogonal channels at 10.7-12.75 GHz and 10.3-11.9 GHz, respectively, while a single-polarized signal is transmitted at 14-14.5 GHz. To obtain good isolation between the transmit (Tx) and receive (Rx) channels of the same polarization with a compact size, an irregularly shaped diaphragm is proposed as a compact dual-function resonator, which has one transmission zero at the Tx band and one pole at the Rx band. The designed OMT is fabricated and measured in a back-to-back configuration. Measured results agree very well with simulated ones and the isolation improvement by the diaphragm is about 15 dB, which verifies our design.
