This article presents a low profile wideband top-loading monopole antenna with a ring and four small post-shape plates. And an inserted ring-shaped plate makes a gap from the post element and leads to enhance wider and higher gain than the conventional top-loading monopole. Four small post-shape plates also lead to obtain higher antenna gain, uniformity radiation patterns. Moreover, top-load also leads to reduce the height of antenna (a small antenna size). The experimental impedance bandwidth is approximately 1.55-2.73 GHz (% bandwidth is 55.14%) below with VSWR 2.0. This antenna also presents a wideband, a uniformity radiation patterns characteristic, respectively. The proposed antenna can be applied PCS, DCS, IMT-2000, WLL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
