This paper presents a compact, tri-bands, rectangular patch antenna based on H-Tree fractal slots structure for modern wireless communication systems has been introduced. The antenna structure consists of a 70.70×56mm2 rectangular patch printed on 173×173×1.6mm3 FR4 substrate. H-Tree slots fractal geometry with the defective ground plane on the other side to enhance gain and bandwidth. The suggested antenna is fed by a 50 Ω microstrip line. The antenna shows three resonance frequencies: 0.784, 1.158, and 1.772 GHz. The suggested antenna offers a total size reduction of about 75 %. The designed antenna possesses fractional bandwidths of 3.976 %, 7 %, and 2.7866 % for the first, second, and third resonances, respectively. Finally, the proposed antenna is a candidate for Global System for Mobile communications (GSM).
