Abstract: A compact multiband Minkowski-Like Pre-Fractal (MLPF) microstrip patch antenna is proposed.This antenna is designed for GPS (L1), PCS, IMT-2000 and WLL frequency bands. Space-filling and self-similarity properties, the antenna possesses, result in a considerable size reduction and multiband operation as compared to the conventional microstrip antenna. The resulting antenna is characterized by a compact overall dimension applicable for use in cellular mobile handset. The antenna is a dual probe-fed Minkowski-like pre-fractal patch of iteration two. The high degree of freedom the proposed design offers, makes it possible to present and analyze many antenna structures. Simulations are carried out using EMSightTM from Applied Wave Research, which is based on the Method of Moments (MoM). Computed bandwidths are 1.48 to 1.61MHz and 1.64 to 2.56 GHz for S11 less than -10 dB. These bandwidths cover the GPS (L1), IMT-2000, WLL and 3G-PCS WLAN IEEE 802.11b at 2.4 GHz frequency bands with accepted radiation characteristics.
