An analysis of UWB double sided circular disc bow-tie antenna

In this paper, presented a single double-sided circular disc bow-tie antenna for Ultra Wide Band (UWB) communication is being proposed. The antenna designs have been simulated using CST Microwave Studio. The antennacovers the UWB spectrum from 3.1 to 10.6 GHz, and had a return loss below than 10 dB throughout the entire band.A compact antenna area of 30.0 × 60.0 mm

is obtained. The material used is FR-4 epoxy glass substrate that has dielectric constant, ε
_r
= 4.4 and the dielectric thickness; h = 1.6mm. The antenna also gives omnidirectional radiation characteristics with reasonablegain values over the same frequency band.
