Abstract

A simple semicircular‐patch bandpass filter (BPF) is presented in this letter. The slot between two semicircular‐patch resonators provides DC blocking and a strong coupling, while the slotted orthogonally feed lines are used to obtain the dual‐mode characteristics. Measurement demonstrates the proposed design methodology and filter. As we know, this is the first report on the microstrip dual‐mode BPF using semicircular‐patch structure. © 2007 Wiley Periodicals, Inc.

## Abstract A novel dual‐mode DC‐block bandpass filter (BPF) using a pair of V‐shape slots on triangular‐patch resonators is developed in this letter. The V‐shape slots perturb the field distributions of triangular‐patch resonators and excite degenerate modes. Compared to our previous research, the

## Abstract A novel design of a compact bandpass ring slot filter for achieving dual‐mode operation is proposed and experimentally studied. By using an arrow‐shaped slot structure as a resonator, the resonant frequency of the proposed filter is significantly lowered, which can lead to a large filte
