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 length of input/output (I/O) lines of the proposed filter is reduced so that the circuit becomes compact. Finally, the good agreement between the simulated and measured results of the proposed BPF is presented. © 2007 Wiley Periodicals, Inc.
