Abstract :
This paper presents a direct TM01-TE11 small mode converter using a circular waveguide with tilted structure for X-band high power microwave system. It is designed to transmit microwave energy from a relativistic backward-wave oscillator (RBWO) source to horn antenna effectively, with optimized geometry through a parameter study. The simulated and measured results of return loss, fractional power of each mode, impedance bandwidth, and mode pattern are provided.
