Square Shaped Fractal Antenna for Multiband Applications

Abstract

In this paper, A square shaped fractal microstrip antenna with first iteration and coaxial feed is presented. The proposed antenna has been designed using FR4 substrate with dielectric constant 4.4 and loss tangent 0.002 and confirms multiband characteristics with directional radiation pattern. The resonating frequencies achieved are 2.45GHz, 4.6GHz & 6.6GHz with a S ₁₁ value less than -10dB. Antenna efficiency of 65% is achieved. The designed and fabricated results are in good agreement with each other. Proposed antenna operates in ISM and C-band thus it is an appropriate candidate for WLAN, Wi-Fi, cordless communications and radar applications.
