Analysis of novel small antenna for wideband transmission

Abstract

Electrically small antennas have been an important part of communications engineering since the beginning. Whether they are small compared 1:0 the extremely long wavelengths used at the lowest radio frequencies, or intended to save space in GHz-range wireless devices, the basic principles are the same. This paper introduces antenna designs for Ultra Wideband 3.1-10.6 GHz communications. The inherent potential of Ultra Wideband systems and techniques for use in communication was demonstrated in various ways by many researchers in the past. An effort made in the direction of utilizing the entire wideband spectrum is presented through this paper. The antenna exhibits a -10 dB return loss bandwidth over the entire frequency ban. The antenna is designed on FR4 substrate. The proposed antenna designs and performances are analyzed using a soft High Frequency structure Simulator (HFSS).
