A PLANAR U TYPE MONOPOLE ANTENNA FOR UWB APPLICATIONS

TLDR

The paper proposes an ultra‑wideband U‑type monopole antenna fed by a coplanar waveguide. The antenna is a low‑profile, compact U‑type monopole (14.48 mm × 28.74 mm × 0.8 mm) that achieves a 3.08–12.75 GHz impedance bandwidth tunable through substrate permittivity, thickness, and feed/ground dimensions, with a parametric study provided. Simulation results confirm the antenna’s wide bandwidth and tunability.

Abstract

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 provides an wide impedance bandwidth ranging from 3.08 GHz to about 12.75 GHz adjustable by variation of its parameters, such as the relative permittivity and thickness of the substrate, width, and feed and ground plane dimensions. Parametric study is presented. Details of the proposed ultra-wideband design are described. Simulation results are presented and discussed in this paper.
