A low cost, compact antenna is a new exemplar in communication. Fractal geometry, a concept in mathematics is adopted to design a miniaturized low profile fractal antenna. The size of the antenna is 38.734 mm × 28.757 mm × 1.6 mm. The antenna is designed in such a way to operate at ISM band, Bluetooth, IEEE 802.11 and IEEE802.15, PCS(1900), GSM lowerband, DCS, UMTS(2100) and WLAN wireless applications. The prototype of developed antenna exhibits wideband characteristics and provides a good agreement of returnloss (S11) −30 dB. Experimental returnloss has been compared with the one which is obtained using method of moments. The main objective of implementing self-similar fractal concept in antenna design makes it flexible in controlling the resonance and bandwidth. This paper is aimed at examining the self-similar concept of fractal geometry with modified approach for wideband characteristics. The prototype of the proposed model with a good agreement of return loss is reported.
