Abstract
In this paper presents the design of a circular microstrip fractal antenna (CMFA) loaded with parasitic edge-coupled (EC) split ring resonators (SRR) and defected ground structure (DGS). The basic resonant structure is a circular patch antenna designed at 3.2 GHz on FR4 substrate with relative permittivity 4.4, and 1.6 mm thickness. One iteration of circular patch and slots is employed to form it fractal and so as to attain multiband performance, the antenna is inset fed by a 50? microstrip line. Further the work is extended to demonstrate the effect of placing split ring resonator to particular position of substrate, improves the impedance matching leading to improved bandwidth. In addition L shaped defected ground structures are used to improve the antenna performance. . A comparison between fractal antenna with and without SRRs and DGS is made and the results verifies that a better gain improvement and return loss. The dimensions of the antenna are 45 mm x 45 mm and it can be used for ultra wide band (UWB) applications.
