Abstract—This paper presents a planar microstrip-fed tab monopole antenna for ultra wideband wireless communications applications. The impedance bandwidth of the antenna is improved by adding slit in one side of the monopole, introducing a tapered transition between the monopole and the feed line, and adding two-step staircase notch in the ground plane. Numerical analysis for the antenna dimens...

In this article, a novel wideband planar monopole antenna for applications in 2.4 GHz Bluetooth and UWB bands is presented and investigated. The low-profile antenna comprises an approximate rectangle patch for covering the UWB band (3.1 ∼ 10.6GHz). A lower pass band, 2.4 GHz Bluetooth band (2.4 ∼ 2.484GHz), can be realized by adding a pair of U-shaped parasitic strips bilaterally beside the fee...

A simple and compact microstrip line -fed ultrawideband planar monopole antenna with single band-notch characteristics is presented. Wide impedance bandwidth is achieved by inserting two rectangular slots on both sides of the microstrip feed line on the ground plane. Band notching is achieved by embedding a half wavelength C shaped slot on the radiator. The antenna is investigated numerically a...

A compact dual band-notched Ultra-Wideband antenna with sharp band-notched characteristics and controllable notched bandwidths is presented. The antenna consists of a spade-shaped microstrip-fed Ultra-Wideband planar monopole antenna and two sets of band-notched structures. The band-notched structures are employed to generate the desired lower and upper rejection bands with good frequency selec...
