UWB Bowtie 2 × 2 array antenna for UWB mobile communication system

In this paper, presented an array of 2 × 2 UWB Bowtie antennas for Ultra Wide Band (UWB) mobile communication is being proposed. The antenna designs have been simulated using CST Microwave Studio. The antenna covers the UWB spectrum from 4.0 to 10.6 GHz, and had a return loss below than 10 dB throughout the entire band. A compact antenna area of 56.4 × 76.0 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 omni directional radiation characteristics with reasonable gain values over the same frequency band.
