Slots or defects integrated on the ground plane of microwave planar circuits are referred to
as Defected Ground Structure. DGS is adopted as an emerging technique for improving the …

This article presents a printed antenna owing the advantages of compact size and simple
geometrical configuration for fifth-generation (5G) 28 GHz communication systems. For …

This study uses annular circular rings to create multi-band applications using crescent-
shaped patch antennas. It is designed to be made up of five circular, annular rings nested …

In this paper a novel structure of an annular ring patch microstrip antenna based on Shape
of Crescents Moon (SCMs) is designed, simulated and measured to operating with …

Abstract The term “ultrawideband”(UWB) in antenna research has become a buzzword over
the past decade. In recent years, advancement in this new area has given birth to numerous …

In this article, a low‐profile bowtie shaped planar antenna loaded with long wire is designed,
analyzed, and fabricated, which is fed by microstrip line and presented with and without …

A compact 2× 2 ultra wideband (UWB) antenna array, composed of four planar rectangular
monopoles, with a novel feeding network scheme is presented. The feeding network …

In this work, new structures of circular microstrip antenna based on slots are designed and
simulated to operate with triple band applications. These slots are annular ring and …

A miniaturized UWB antenna with multiple notch bands is proposed for modern wireless
applications. The proposed microstrip-line-fed antenna consists a Y-shaped strip supported …

The development of Defected Ground Structures (DGS) and Slab microstrip Structures
(SMS) techniques improved the properties of numerous microwave devices. While the DGS …
