A compact size low profile microstrip-fed crossed monopole antenna for ultra wideband communication is presented. The impedance bandwidth of a microstrip crossed monopole antenna has increased with a suitable dimension of ground plane and rectangular patch. The aim of this paper is to improved bandwidth and return loss of a Crossed Monopole Microstrip patch antenna and study the effect of anten...
A high performance monopole antenna fabricated using a folded wire line and metal patch as radiator is presented. A prototype of the proposed monopole antenna with a compact area size is implemented, and the multi-band WLAN antenna shows a wide operating bandwidth of about 530MHz and 3400MHz for low band and high band, bandwidth, making it easy to cover the IEEE 802.11a, IEEE 802.11b, IEEE 802....
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...
A compact UWB monopole band-notched antenna with simple structure and small size is proposed and studied in this article. The size of the antenna is 33 3 29.6 3 1.6 mm. The proposed antenna has an impedance bandwidth (VSWR< 2) at 3.1–10 GHz, except the bandwidth at 3.3–3.7 GHz and 5.15–5.82 GHz for WLAN and WiMAX application. A notch in the ground plane is used to obtain a frequency band-notche...
A P-shaped monopole antenna (PSMA) attached with a glass substrate is proposed for wireless body area networks (WBAN) applications. The study investigates the performance of PSMA above reflection plane substrates with di erent material of glass and a perfect electric conductor (PEC). The PSMA prototype is fabricated on the FR4 substrateto be operated between 3.1 to 5.1 GHz frequency band. It is...
In this communication, a new compact UWB monopole antenna with dual band rejection is presented. The antenna is designed using FR4 substrate with dielectric constant 4.4, loss tangent 0.02 and a height of 1.59 mm. Initially the UWB antenna is designed to obtain a 153% fractional bandwidth from 2.4 GHz–21.7GHz. The ground plane beneath the patch is etched out and a rectangular slot is introduced...
