Abstract :
In this paper, we present the design of tilted slot milled on the broad wall of a twisted waveguide for the first time. The proposed structure consists of a standard WR-90 waveguide twisted with 360 degree. A single slot is designed on the broad wall of the twisted waveguide. Based on the design a twisted waveguide antenna is simulated with EM simulator. The proposed antenna shows -10 dB impedance bandwidth of 0.92GHz and fractional bandwidth of 10.12% (8.63-9.55 GHz). The simulated gain is 7.55 dBi is achieved.
