Abstract

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 nonorthogonal feed lines. © 2009 Wiley Periodicals, Inc.

## Abstract A microstrip bandpass filter using a dual‐spiral configuration is proposed. Unlike conventional filter topology, this filter is integrated directly within 50Ω microstrip lines. The filter has a simple configuration, and compact size, and is easy to fabricate. Two transmission zeros clos

## Abstract This paper presents a new compact and simple microstrip‐patch bandpass filter structure using only one resonator. This filter has two transmission zeros on the both sides of the passband. The volume of this filter is about 1/3 or 1/2 of a conventional filter. Because the new filter is w

A novel dual-mode microstrip filter operating at 900 MHz is proposed using degenerate modes of a microstrip-loop resonator. The resonator structure that is formed of meandered microstrip-line elements has a smaller size than the other dual-mode microstrip resonators in the literature. The dual-mode

A novel microstrip transversal bandpass filter is proposed by replacing the full-wavelength resonator with two shorter resonators; in order to achieve simultaneous spurious response suppression and dual zero implementation. These two zeros can be easily tuned by the above resonators. A prototype fil

## Abstract In this letter, a compact and high selectivity dual‐band dual‐mode microstrip bandpass filter (BPF) with the source‐load coupling is proposed using the single short‐circuited stub‐loaded stepped‐impedance resonator.The resonator can generate two resonant modes in each band. The short‐ci
