Abstract

A bandpass filter that uses broadside‐coupled structures and covers the ultra‐wideband (UWB) frequency range (3.1–10.6 GHz) is presented.It utilizes a broadside‐coupled microstrip‐slot‐microstrip structure with embedded low‐pass filter to achieve the required UWB performance. The simulated and measured results of the proposed filter prove its UWB performance with about 0.4‐dB insertion loss, more than 17‐dB return loss, and less than 0.3‐ns peak‐to‐peak deviation in the group delay across the UWB passband. The filter has a wide high cutoff band that extends beyond 20 GHz. It has a compact size with overall dimensions of 1.5 × 2.5 cm^2^. © 2011 Wiley Periodicals, Inc.

## Abstract An ultra‐wideband (UWB) bandpass filter is proposed based on the hybrid structure of microstrip and coplanar waveguide (CPW). First, the detached‐mode resonator is formed on the CPW layer, which composes a quarter‐wavelength (λ/4) multiple‐mode resonator (MMR) with a short‐stub and a λ/

## Abstract An ultra wideband bandpass filter with sharp‐rejection is proposed by using a new structure of double ring resonators. The double ring resonator generates a couple of attenuation poles, and its operation mechanism is made clear through the even‐ and odd‐mode analysis of the circuit. The
