Abstract

In this paper, we study the size effects of an Hโ€shaped defected ground structure (DGS) cell upon the characteristic impedance of a microstrip line, by using a simple circuitโ€analysis method. An LC model of an equivalent circuit can represent the proposed Hโ€shaped DGS cell. It is found that the characteristic impedance of a 50ฮฉ microstrip line can be controlled easily in a wide range by using the Hโ€shaped DGS cell. ยฉ 2004 Wiley Periodicals, Inc.

We have proposed a CPW-fed meander-type slot antenna, which has a nonuniform slot-line width. The resonant frequency of the antenna has been decreased from 2.50 to 1.94 GHz without changing the dimensions. By increasing the meander sections, the resonant frequency of conventional antennas has been d

A full-waue approach based on the spectral-domain method is applied to a cylindrical strip line and a microstrip line. The effects of the dielectric substrates and the size of the cylinder are taken into account by the spectral-domain Green's functions. Numerical results showing the characteristic i

## Abstract Impedance matching of a loaded microstrip transmission line is performed by using only parasitic elements. By the term โ€œparasiticโ€ matching element we mean that there is no physical connection between the conductors of the matching subsystem and the conductors of the main circuit. We co
