Broadside-Coupled Microstrip Lines as Low Loss Metamaterial for Microwave Circuit Design

Compact Two-layer Microstrip Bandpass Filters Using Broadside-coupled Resonators

This paper presents a design methodology for realizing broadside-coupled microstrip bandpass filters on multilayer substrates to reduce the size of the filter. The new filter configuration consists of broadside coupled split-ring resonators on two layers backed by a ground plane. With the proposed new method, miniaturization to a greater extent can be achieved compared to the conventional metho...

Design of Metamaterial Textures for Microwave Applications

Closed-Form Asymptotic Extraction Method for Coupled Microstrip Lines - IEEE Microwave and Guided Wave Letters

The effective dielectric constants of a symmetric coupled microstrip line operating in the dominant mode are solved by using a closed-form formula of the asymptotic part of the impedance matrix elements. Using this asymptotic closedform solution, the finite upper limit for numerical integration in the evaluation of the impedance matrix elements is significantly reduced. This results in improved...

Electrically Small Resonators for Planar Metamaterial, Microwave Circuit and Antenna Design: A Comparative Analysis

Planar metamaterials and many microwave circuits and antennas are designed by means of resonators with dimensions much smaller than the wavelength at their resonance frequency. There are many types of such electrically small resonators, and the main purpose of this paper is to compare them as building blocks for the implementation of microwave components. Aspects such as resonator size, bandwid...

Miniaturized Microstrip Bandpass Filter Using Coupled Metamaterial Resonators

A compact microstrip band pass filter using metamaterial resonators is proposed and implemented, aiming at high level of miniaturization, low cost and ease of fabrication. Some considerations in order to improve and control the coupling coefficients between resonators are exposed. The magnetic and electric character of the coupling coefficient is analyzed in detail.
