This paper focuses on a tutorial overview of defected ground structure (DGS). The basic
conceptions and transmission characteristics of DGS are introduced and the equivalent …

An ultra-wideband (UWB) U type monopole antenna fed by a coplanar waveguide (CPW) is
proposed. It has low profile and very compact size (14.48 mm× 28.74 mm× 0.8 mm). It …

In this paper, a technique of adding small fractal elements to the polygon shape radiator of a
CPW-fed monopole antenna for bandwidth enhancement is proposed and experimentally …

In this paper a novel rose leaf shape microstrip antenna with capacitively coupled
rectangular fed is presented. Various shapes of capacitive coupled fed are compared and …

In this paper, a new compact circular monopole ultrawideband antenna with multiple narrow
bands notched is proposed, which is implemented by using the existing techniques, such as …

A new defected ground structure (DGS) is firstly proposed in this paper, which has better
slow-wave effect than that of cross or dumbbell one. Using the model of transmission line, its …

A novel compact Archimedean spiral antenna with gaploading is investigated in this paper.
A circular frame sharing the same centre with the spiral elements introduces a capacitive …

This paper presents a new ultra wideband bandpass filter which is implemented using
defected microstrip structures (DMS). This wideband bandpass filter consists of a cascade …

This paper presents two design compact hexagonal monopole antennas for ultra-wideband
applications. The two antennas are fed by a single microstrip line. The Zeland IE3D version …

Microwave Imaging (MI) and Body Area Networks (BANs) technologies are widely used in
healthcare systems. A dual-functional compact ultrawideband (UWB) antenna with a high on …
