摘要
Circular holes are etched off of a microstrip disk resonator. This results in a reduction of 30% in size. By offsetting the positions of some of these holes, degenerate orthogonal mode is excited, resulting in a split-mode bandpass filter. This filter can be considered as a lattice-type structure. A filter with a bandwidth of 8% centered at 2.0 GHz was designed. The measured insertion loss is 0.6 dB.
