A novel CPW-fed ultra-wideband antenna design

TLDR

The study presents a novel CPW‑fed ultra‑wideband antenna designed, fabricated, and measured for UWB communications. The antenna is fabricated on a 0.762‑mm TMM4 substrate (εr = 4.5) and engineered to operate from 3.1 to 8.3 GHz. Measurements show nearly constant insertion loss across the band and group‑delay variation below 1 ns, indicating suitability for UWB applications. © 2005 Wiley Periodicals, Inc.; DOI 10.1002/mop.20646.

Abstract

A novel ultra-wideband (UWB) antenna fed by coplanar waveguide (CPW) is designed, fabricated, and measured for UWB communications. It is designed to work on a substrate TMM4 of thickness 0.762 mm and relative permittivity 4.5, and to operate from 3.1 to 8.3 GHz. Details of the proposed antenna design and the measured results are presented and discussed. Measured insertion loss is almost constant across the frequency band and the group-delay variation is less than 1 ns, thus indicating that the proposed antenna is a good candidate for UWB applications. © 2005 Wiley Periodicals, Inc.
