Abstract

In this article, an ultra-wide band circular fractal antenna inscribed with square is presented. The prototype of the antenna is fabricated on a 1.6 mm thick FR4 substrate material. In the proposed design, use of partial ground structure and the fractal geometry resulted in a compact size and ultra-wide band (UWB). The antenna’s calculated result reveals UWB characteristics from 2 to 10.8 GHz (137.5%) with almost Omni-directional patterns of radiation and radiation efficiency >80% throughout the operating range. The measured (S-parameter, radiation pattern and peak gain) and simulated results are appropriate with good performance characteristics. A detailed study was conducted for various dimensions of circular patch and the partial ground structure. The antenna is developed and optimized using HFSS simulation tool.
