Abstract

This paper presents a dual‐band bandpass filter by introducing transmission zeroes in the passband of a broadband bandpass filter using square‐loop dual‐mode resonators. The transmission zeroes are achieved by using a dual‐mode resonator. The dual‐mode resonator is attached to two transmission lines of same length. These lines are coupled to similar transmission lines that are attached to the I/O ports. The filter has a compact size, low losses, and good rejection between the two bands. © 2008 Wiley Periodicals, Inc.
