Compact Multiband Planar Fractal Cantor Antenna for Wireless Applications: An Approach

A compact multiband fractal antenna which is a new criterion in communication is proposed. The optimized prototype measures 35 mm x 31 mm x 1.6 mm. The proposed antenna covers WLAN IEEE 802.11b, 802.15, PCS, GSM lower and higher bands, DCS, IMT, UMTS, Wi-Fi, and WLAN wireless applications. The proposed antenna exhibits multiband characteristics with an S-11 of -30.69 dB at design frequency and it is found that similar to 70% of the S-11 graph below -10 dB reference is achieved. Experimental S-11 has been compared with the one which is obtained using method of moments. The aim of implementing self-affine fractal concept in antenna design makes it flexible in controlling the resonance and bandwidth. This paper investigates self-affine fractal geometry to miniaturize and to resonate multiband frequencies. The prototype model with a good agreement of S-11 is reported.
