Abstract: The x-band rectangular waveguide with groove on each side wall is analyzed using finite element method (FEM). By keeping the width and height of the groove fixed, the outer length of the groove is varied. The width of the groove is kept fixed at 0.6 cm, whereas three different groove heights are considered to be 0.2 cm, 0.4 cm and 0.6 cm. The effect of different dimensions of the groove on the cut-off frequencies for the dominant mode TE10 and TE20 as well as on bandwidth is studied. The cut-off frequencies for TE10 and TE20 mode get lowered, whereas the passband is found to be raised.
