A CPW-FED UWB monopole-like slot antenna

Abstract

A simple and compact coplanar wave guide (CPW)-fed ultra-wideband (UWB) monopole-like slot antenna is presented. The proposed antenna consists of a monopole-like slot and a CPW circular patch with feeding stub structure, which is etched onto an FR4 printed circuit board (PCB) with an overall size of 25 mm× 25 mm ×1.6 mm. The simulation results shows consistent radiation patterns and impedance bandwidth over an entire operating frequency from 3.1 10.7 GHz.

Improved designs of antennas, power dividers and antenna arrays using modified Gielis curves

“…Another compact CPW-fed UWB monopole slot antenna with pentagon-shaped ground slot has been used as a UWB radiator, in which a circular disc is connected to a feeding stub and is encapsulated by the ground plane [58]. Using circular/elliptical slots with a modified circular tuning stub and a notched ground plane can help to provide UWB characteristics.…”
