Design of printed rectangular monopole antennas for UWB applications

Abstract

1Ultra wide Band (UWB) technology is one of the most promising solutions for future communication systems due to its high-speed data rate and excellent immunity to multi-path interference. The frequency range for UWB systems approved by the FCC is between 3.1 and 10.6 GHz. The printed antenna is designed to cover the UWB in particular, the lower band of 3.1-5 GHz. It is a well known concept that the bandwidth of wire antenna can be increased by increasing the diameter, thickness of wire. This concept is tried here to enhance the bandwidth by increasing the size of the monopole by different sizes and geometries.In this paper, Wide Rectangular Patch is considered and tested its response for UWB applications,and this patch is loaded with one left strip at bottom of the patch on one side and then it is loaded with two strips on either side of the patch,and the three prototypes are tested and their reponses are compared.

Investigation of A Novel Dual Band‐Notched UWB Antenna by the Equivalent Circuit Model and Time Domain Characteristics

“…Printed monopole antenna, due to the simple structure, wide bandwidth and nearly omnidirectional radiation patterns, has been widely used in UWB antenna design. Various types of planar antennas have been developed with many various shaped planar elements, such as rectangular , circular , elliptical , fan‐shaped , and invert triangle for UWB applications.…”

Proposal of MIMO Ultra-Wide Band Antenna with Low Mutual Coupling

“…Considering the design in [13] by Kumar et al: a substrate of FR4 with ε r = 4.3 and tan δ = 0.02 was used; the dimensions are 60 × 45 × 1.6 mm 3 and ground plane made of copper with the thickness of 35 µm, however, that antenna structure is fairly big. Based on the structure in [13], the authors proposed an antenna 1859-378X-2014-3406 c 2014 REV 99 with smaller size, more compact and simpler structure that serves as radiation elements for the MIMO UWB antennas.…”
