Abstract :
This study was carried out to design, simulate, and develop an ultra wideband (UWB) fractal microstrip patch antenna (MPA). The antenna designed for broadband telecommunications had smaller dimensions, omnidirectional pattern, and good gain/return loss. The miniaturization was realized through a metamaterial transmission line and antenna power supply by an electromagnetic coupling system. In order to cover the desired frequency bandwidth, a new fractal was designed and combined with the circular polarization of disturbances in certain parts of the fractal structure. Furthermore, the quality of antenna bandwidth was improved deforming the ground plane. Finally, the results of the development, simulation, and measurement of input return losses and radiation patterns were explored. The results demonstrated that the proposed model involves a compact, simple fractal MPA that provides ideal bandwidth and impedance matching.
