A Compact Dual Band-notched Circular Ring Printed Monopole Antenna for Super-wideband Applications
In this article, a simple and compact dual bandnotched (DBN) super wideband (SWB) printed monopole antenna (PMA) has been proposed. The proposed antenna composed of a circular PMA, which is connected through a 50-Ω triangular tapered microstrip fed line (TTMFL) and a round-cornered finite ground plane (RCFGP). It exhibits a very wide frequency band from 1.6–25 GHz (ratio bandwidth of 15.63:1) w...
متن کاملA Compact Printed Triangular Monopole Antenna for Ultrawideband Applications
In this article, a printed triangular-shaped monopole antenna is proposed for emerging ultrawideband application. The proposed antenna uses a triangular radiating patch which is directly fed by a 50-X microstrip feed line. To improve the impedance bandwidth, a round-corner ground plane has been used. To further improve the impedance bandwidth for the entire band, a microstrip transition (near t...
متن کاملA Novel Ultra-Wideband Printed Monopole Antenna
In this paper, we introduce a novel printed monopole antenna for ultra-wideband (UWB) applications. The antenna is composed of two overlapped circular disc monopoles with a finite ground plane and fed by a 50 microstrip line. The designed antenna operates over impedance bandwidth (2.9 to 11.6GHz) for return loss S Ω 11 < -10dB. The antenna also shows omni-directional radiation patterns and good...
متن کاملA Broadband Suspended Microstrip Antenna for Circular Polarization
In this paper we propose a circularly polarized (CP) microstrip antenna on a suspended substrate with a coplanar capacitive feed and a slot within the rectangular patch. The antenna has an axial ratio bandwidth (< 3 dB) of 7.1%. The proposed antenna exhibits a much higher impedance bandwidth of about 49% (S11 < −10 dB) and also yields return loss better than −15 dB in the useful range of circul...
متن کاملA Simple Broadband Printed Antenna
This paper presents a simple broadband proximitycoupled microstrip patch antenna. A circular patch is used as the main radiator, and an H-shaped shot is cut in the ground plane below the feed line. A stepped-width microstrip line is used to feed the patch through proximity coupling. By using a single patch, the prototype antenna achieves an impedance bandwidth of 26%. Low cross-polar levels bel...
