A Miniaturized Wideband Fractal Patch Antenna for pes Applications (1850-1990 MHZ)

In this paper a novel fractal shape structure is introduced. Application of the proposed fractal shape to a square patch antenna represents a very good reduction size in comparison to the previously reported works. To compensate for the reduction in the antenna bandwidth, which occurs during the miniaturization process, the Tprobe feeding method is used. By using this feeding method, the impedance bandwidth of the antenna is increased , which makes the antenna appropriate for PCS applications in the frequency range ofGSM 1900. The effects of various parameters of the feed structure on the input impedance of the antenna are also presented in this paper . In order to validate the simulation results , the antenna was fabricated. The results of testining and measurments of the fabricated antenna in the antenna Labarotary of Iran Telecommunication Research Center (ITRC) verified the simulation results .
