This paper tells how to construct rectangular monopole antenna which will be printed on printed circuit board (PCB). The antenna behaves as planar monopole antenna as it has rectangular patch and ground plane which lies in same plane of PCB. Also this antenna is a broadband antenna because its ratio bandwidth lies under broadband category. In comparison with monopole antenna broadband planer mo...

In this article, a novel dual-band microstrip monopole antenna based on split-ring elements is proposed for WLAN (2.4/5 GHz) applications. The antenna fed by a two-stage microstrip line has fairly small dimensions and provides 7.5 and 25.5% impedance bandwidth performance at the respective bands. Also, the antenna exhibits almost uniform radiation patterns at each frequency band. The measuremen...

This paper describes the comparision of a microstrip-fed monopole ultra wideband antenna with and without notch. In case of notch the notch-band characteristics is achieved by Cshaped ring resonator. The paper gives better understanding of antenna parameters such as return loss, VSWR etc., and its variation in performance of antennawith and without notch. Also presents the effect of parameters ...

New methods are presented for increasing the bandwidth of wire antennas using impedance loading. This paper extends the seminal Wu-King theory of the internal impedance profile that produces travelling-wave only current modes on a center-fed dipole antenna. It also presents a numerical optimization methodology based on Central Force Optimization, a new deterministic multidimensional search and ...

In this paper, a novel compact and wideband fylfot-shaped planar monopole antenna is proposed. The fylfot-shaped is suggested to reduce the volume of a general crossed planar monopole antenna. The volume of the proposed antenna is about 1/4 of a general crossed planar monopole antenna under the conditions where the wideband characteristics are maintained. This technique is suitable for the desi...

Abstract— Study of a novel planar circular disc monopole ultrawide-band antenna fed by coaxial line is presented in this paper. The radiator, ground plane and the feeder equipment of the antenna are placed on the same plate. The special structure reduces the spatial volume, and it is used to realize the miniaturization of the antenna. The basic theory and design method are analyzed, and detaile...

This paper presents an investigation of split ring resonator (SRR) parameters on a coaxial-fed monopole antenna. The adding of SRR slot can create a notch in the result of coaxial-fed monopole antenna design. Thus, this paper aims to investigate the effect of changes to the outer ring radius and slit cut width of the SRR slot. All antenna designs and simulations involved are drawn and simulated...
