Abstract

The modified cross‐coupled spiral resonators with Hilbert configuration are introduced for a large coupling coefficient in this article. For comparison, the conventional cross‐coupled spiral resonators are fabricated and measured herein. To obtain low insertion loss (−0.27 dB), high out‐of‐band rejection level (−19.5 dB) and wider FBW (50.9%), the filter of simplified CCSR‐H is proposed. Results included surface current distribution and frequency responses are presented and discussed. © 2007 Wiley Periodicals, Inc.

## Abstract A novel compact half‐wavelength cross‐coupled stepped‐impedance resonator filter using low‐temperature cofired ceramic (LTCC) technology is presented. The filter not only has good selectivity due to the controllable transmission zeros but also has a small size by the virtue of LTCC stru

## Abstract In this letter, a multilayered dual‐band bandpass filter (BPF) using cross‐coupled stepped impedance resonators (SIRs) is designed and implemented. By determining the impedance ratio (K) and physical length (α) of the SIRs, the dual‐band response at 2.4/5.2 GHz can be achieved. Cross‐co
