Analysis and Design Rectangular Patch with Half Rectangular Fractal Techniques

In this paper, rectangular patch with half rectangular fractal geometry is designed. The proposed antenna is fabricated on RT/duroid 5880 with relative permittivity 2.2 and having dimensions 40 mm x 30 mm x 1.56 mm. HFSS software is used for the design of this antenna. It operates at four frequency bands 3.19-3.29 GHz, 3.98-4.09 GHz, 5.4-5.46 GHz and 5.97-6.06 GHz. The proposed antenna can be used in the military for meteorological purpose and satellite communications. The proposed design has return loss –18.5061 dB, -22.1394 dB, -4.7404 dB and -36.2199 dB in frequency bands 3.19-3.29 GHz, 3.98-4.09 GHz, 5.4-5.46 GHz and 5.97-6.06 GHz.
