Abstract: In this paper, a compact TE21 mode coupler is designed for tracking Low Earth Orbit Satellites. The tracking feed has to be employed to provide the error signal to servo systems feedback mechanism. The design incorporates the circular and eight rectangular waveguides with 13 asymmetric circular apertures on a single rectangular arm. The arrangement is small in size provides good return loss and VSWR The designed configuration presents return loss is better than -30dB and VSWR around 1.06 for frequency range of 25.5-27GHz. The designed model is simulated and analysed using CST.
Keywords: Autotracking TE21 mode coupler, coupling aperture, satellite communication.
