Broadband omnidirectional U-shaped metal-plate monopole antenna

Abstract

This paper presents a new broadband omnidirectional monopole antenna. The antenna is a U-shaped metal-plate monopole antenna that is easily fabricated by bending a rectangular metal plate. The antenna can provide a very wide operating bandwidth of larger than 5 GHz (about 2.0 to 7.1 GHz). In addition, for frequencies across the operating bandwidth, good omnidirectional radiation is obtained. Details of the antenna design are described, and experimental results of the constructed prototypes are presented. © 2005 Wiley Periodicals, Inc.
