Abstract
For S-band applications, a microstrip fractal antenna is designed by extending narrow impedance bandwidth into wide impedance bandwidth with use of partial ground plane. In the designed fractal antenna, the six elliptical slots in ground plane and two elliptical slots in radiating patch are embedded to improve the depth of return loss. Further, the parametric study is performed on width of microstrip feeding line, position/size of ellipses in radiating patch and ground plane to achieve mismatch loss [Formula: see text] 0.044[Formula: see text]dB and power delivered to antenna 99%, i.e., return loss [Formula: see text][Formula: see text]dB for S-band. The simulated antenna results are obtained using electromagnetic solver software and fabricated antenna results are measured using Vector Network Analyzer Bench MS46322A and they are found to be in good agreement.
