| Abstract: | Without any perturbations on the surface of the patch resonator or orthogonal feed lines, a new microstrip dual-mode triangular-patch bandpass filter with low insertion loss and one transmission zero is presented. The degenerate modes are realised by use of the input/output spur-lines. It has been verified by simulation and measurement. |
