Compact Multi-Resonant Patch Antenna with Fractal Slots Inspired by Smith Chart Configuration

This paper describes the design and analysis of a multi-resonant compact patch antenna with fractal slots on the basis of Smith Chart geometry for indoor communication systems. A (70mm x 70mm x 4 mm) single circular patch antennas with periodic fractals in the form of combined r and x circles is capable of resonating at some desired sub-bands starting from GPS to WI-MAX with good enough directional characteristics greater than 3 dB in average within the whole frequency band. The dielectric material used for the proposed Microstrip patch antenna is Rogers RO3006 with dielectric constant of 6.15 and the patch is made up of perfect electric conductor (PEC). The proposed fractal geometry possesses multiband behavior at 1.35 GHz, 1.52 GHz, 2.2 GHz, 2.55 GHz, 3 GHz, 3.47 GHz 3.66 GHz, 4 GHz and ultra-wideband from 4.16 GHz till 6 GHz. In comparison with the already existing antenna systems in the wireless market for similar purposes, the proposed antenna has considerably shown better performance and supplementary compactness which makes it competitive among other antenna models.
