Abstract

A 30.5 GHz circular transition used to transmit TE01 mode is proposed because of no suitable one available. Calculations and simulations indicate that it can transmit TE01 mode with transmission efficiency over 0.99 (within a bandwidth of 3 GHz). At the same time, the good performance of it has been demonstrated in experiment. Furthermore, the transition has only a length of 80 mm much shorter than linear or the other nonlinear ones. Such short length is very helpful for construction of a compact microwave device.
