Abstract

This paper presents a novel, compact, low‐insertion‐loss, sharp‐rejection, wideband microstrip bandpass filter. The filter is based on a ring resonator with direct‐connected orthogonal feed lines, and uses two stepped‐impedance open stubs to construct a wideband passband with two sharp stopbands. The unit cell of the ring resonators is easily cascaded and also has the feature of a compact structure. The filter is designed to reduce interference in full‐duplex systems for satellite communications. © 2005 Wiley Periodicals, Inc.

## Abstract In this article, we present a novel compact dual wideband bandpass filter (BPF) by using a new structure of ladder stub resonator (LSR). The proposed LSR can produce attenuation poles to form low loss and dual‐wideband bandpass response. By tuning the structure parameters of LSR, the du

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
