An Asymmetric Liquid Crystal Polymer Based Fractal Slotted Uwb Monopole Antenna With Notch Band Characteristics

Abstract

An improvement of the fractal antenna is made to enhance its gain and bandwidth. In this paper, a relative study of the fractal antenna which is excited by the CPW is done. The antenna that we proposed was designed and simulated using HFSS. Using the fractal concept and CPW-feed technique the compact size and the ultra wideband impedance matching is obtained. The final dimensions of the designed antenna measure 36.4mm x 40mm x 1.53mm.A low-cost FR-4 substrate is used in this design. The UWB characteristic of the antenna ranges from 3.137GHz-11.4332GHz with a notch band from 3.7716 GHz to 4.07 GHz. The designed antenna is mainly used for the UWB pulse based trans-receiving applications.
