Defected ground structures (DGS) have been developed to improve characteristics of many
microwave devices. Although the DGS has advantages in the area of the microwave filter …

A simple ground plane structure that can reduce mutual coupling between closely-packed
antenna elements is proposed and studied. The structure consists of a slitted pattern, without …

This paper introduces a coupling element to enhance the isolation between two closely
packed antennas operating at the same frequency band. The proposed structure consists of …

An efficient technique is introduced to reduce mutual coupling between two closely spaced
PIFAs for MIMO mobile terminals. The proposed mutual coupling reduction method is based …

A simple ground plane structure that can reduce mutual coupling between closely-packed
antenna elements is proposed. The structure consists of a dumb-bell-like pattern etched in a …

This paper presents a close but a beginner's perspective and a comprehensive review of
microstrip filters with defected ground structure (DGS). The concept of DGS is inspired by …

If you are involved in designing and developing small antennas, this complete cutting-edge
guide covers everything you need to know. From fundamentals and basic theory to design …

This letter presents a microstrip patch antenna integrated with two-dimensional photonic
bandgap (PBG) and one-dimensional defected ground structure (DGS) jointly in ground …

Controlling higher order modes up to third harmonic of the fundamental operating frequency
in a microstrip line-fed patch antenna has been successfully demonstrated. Harmonic …

In this letter, a double U-shaped defected ground structure (DGS) is proposed to broaden
impedance bandwidth of a microstrip-fed monopole antenna. The antenna structure consists …
