摘要：
A novel compact dual-mode microstrip bandpass filter (BPF) with adjustable transmission zero (TZ) is proposed. It is composed of a nested microstrip square-loop resonator. The filter with two TZs in the lower and upper stopbands is designed, fabricated, and measured. A circuitry size reduction of 55% is achieved by the proposed filter when compared with the convention dual-mode filters with non-orthogonal feed lines. (C) 2009 Wiley periodicals, Inc.
