Abstract

In this paper a Dual Band Star fractal antenna with slot is proposed for wireless applications, with a semi-elliptical ground plane. The proposed antenna is designed to operate at two different bands having bandwidth 1GHz and 1.2 GHz at resonant frequencies 2.8 GHz and 5.7 GHz respectively for wireless applications with good return loss and radiation pattern characteristics, in the frequency band. The proposed antenna is fed by a 50Ω microstrip line and fabricated on a low-cost FR4 substrate having dimensions 33.5(L) × 28.5(W) × 1.6(h) mm³ with ε_r and tanδ=0.025. The antenna shows acceptable gain with nearly omni-directional radiation patterns in the frequency band for wireless applications as Wi-MAX and WLAN.
