Feed lines effects on 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 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 antenna feed lines were analyze in order to maximize the performance of UWB antenna. A compact antenna area of 30.0 × 60.0 mm2 is obtained. The material used is FR-4 epoxy glass substrate that has dielectric constant, εr = 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.
