Ground effect analysis for ice cream cone UWB antenna for UWB communication

Abstract

In this paper, presented a ground plane effect performance of an array 2 × 1 Ice Cream Cone UWB Antenna for Ultra Wide Band (UWB) communication is being proposed. The antenna designs have been simulated using CST Microwave Studio. The antenna covers the UWB spectrum from 3.1 to 10.6 GHz, and had a return loss below than 10 dB throughout the entire band. The basic antenna analysis has been done including the analysis of antenna performance due to ground plane effect. A compact antenna area of 70 × 80 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> is obtained. The material used is FR-4 epoxy glass substrate that has dielectric constant, ε <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> = 4.4 and the dielectric thickness; h=1.6mm. The antenna also gives omni directional radiation characteristics with reasonable gain values over the same frequency band.
