Gain Enhancement for Multiband Fractal Antenna Using Hilbert Slot Frequency Selective Surface Reflector
In this paper, the gain enhancement for a multiband antenna with Hilbert fractal slot in a modified rectangular patch is presented.The composite structure including a wide slot, a Hillbert fractal slot with 1st iteration, and modified rectangular patch used as additional resonators producing multi-resonant frequencies are developed.The antenna gain can be enhanced by using frequency selective surface (FSS) reflector.The proposed FSS is optimized to control the phase and the magnitude of Sparameters of reflection and transmission characteristics over a bandwidth suitable for multiband antenna.FSS layer has been designed and employed with a unit cell of Hilbert fractal slot.Experimental results show good multiband operation at the frequency ranges of 870-960 MHz, 1710-1880 MHz, 1.85-1.99GHz, 1.92-2.17 GHz, 2.3-2.36 GHZ and 2.4-2.485 GHz,respectively.Finally, the designed antenna can operate and cover the applications of GSM, DCS, PCS, UMTS, WiMAX and WLAN IEEF802.11 h/g.Moreover, the antenna gains at the operating frequencies of 0.9, 1.8, 1.92, 2.045 and 2.45 GIz are 7.607, 10.41,9.54, 8.67 and 7.98 dBi, respectively.
