This paper presents a dual-mode bandpass filter with asymmetric passband response. Hexagonal shaped Substrate Integrated Cavity (SIHC) has been used to implement the proposed filter. Perturbation technique has been used to realize this bandpass response. The filter has four poles and one transmission zero introduced at the left of the passband. The design has passband insertion loss of 0.65 dB and...
A Dual-mode substrate integrated waveguide hexagonal cavity (SIHC) filter using hexagonal shaped cavity for X-Band application has been proposed in this paper. Use of perturbation technique to achieve dual mode response has been investigated. The field patterns of the degenerate modes and the mode splitting characteristics are also studied. The theoretical analysis with the help of coupling matrix...
