Low‐loss triangular‐patch dual‐mode bandpass filter with slotted input/output
microwave and optical technology letters
Abstract Without any perturbations on the surface of the patch resonator or orthogonal feed lines, a novel microstrip dual‐mode triangular‐patch bandpass filter with slotted I/O is introduced in this letter. The degenerate modes are excited by the use of the slotted I/O. Also, the coupling characteristics of two degenerate modes are studied with respect to main design parameters. A dual‐mode filter with 0.8 dB insertion loss in the passband was designed and fabricated. Measurement verify the validity of the proposed design method. © 2006 Wiley Periodicals, Inc.
