A Design of Crown Square Fractal Antenna Using Transmission Line Feed

The paper presents the designs of a crown square fractal antenna. The propounded antenna is designed on 1.6mm thick FR4 glass proxy substrate with dielectric constant Er of 4.4 and is fed by transmission line. The proposed antenna design helps in reducing the metal usage, save cost and provides good reflection coefficient and good VSWR. Performance of proposed antenna has been analyzed in terms of return loss, VSWR, input impedance, gain, and bandwidth in the 1 GHz to 7GHz frequency range. The proposed antenna provides an impedance bandwidth of 45 % around the resonant frequency of 0.5575 GHz and good return lossof -36.44.
