A novel design of multiband Minkowski fractal patch antenna with square patch element for X and Ku band applications

This paper proposes the Minkowski fractal antenna with square patch element. The substrate used for this design is FR-4 the proposed design whose dielectric constant and thickness is 4.4 and 1.6 mm respectively. This antenna consists of four parts-patch, probe feed, substrate and ground plane. The square patch element is located centrally in the Minkowski fractal patch antenna. The parameters studied in the paper are resonant frequency, VSWR, Return Loss, Bandwidth, Radiation Pattern, Smith Chart and gain. The targeted frequency of this antenna is 8.8 GHz for Radio location application and WPAN (Wireless Personal Area Application). It can be used for several applications in X-band (ranges from 8–12 GHz) and Ku-band (ranges from 12– 18 GHz). The antenna resonates at 8.8 GHz, 10.8 GHz, 13.02 GHz and 15.23 GHz. The maximum gain observed is near about 1.56 dBi. This proposed design is simulated using Computer Simulation Technology Microwave Studio (CST MWS) software.
