Abstract: Miniaturized high gain single-feed multiband patch antenna approach is presented in communication systems. The multiband is obtained by introducing Defective ground structure (DGS) and etching the rectangular slots on the patch. A Single-band antenna with a frequency of 3.8 GHz is primarily, triple-band, Quad-band, and finally Penta-band proposed antennas are designed. The peak gains and efficiencies of the antenna vary from 4.26 to 6.27 dBi and 65% to 91% correspondingly. This proposed design is constructed of a modified rectangular patch antenna with interdigital DGS and two open loop resonators (parasitic elements) to serve as a coupling bridge. The measured results shows that the proposed antenna has impedance bandwidths about 130MHz (1.13-1.26GHz), 80MHz (1.66- 1.75GHz), 480MHz (1.92-2.4GHz), 330MHz (3.64-3.94GHz), 560MHz (9.10-9.66GHz) which meet the requirements of wireless video links, radio applications, digital audio radio service(s-band), Wi-MAX and X-band applications.
