Triple Band Notch Microstrip Patch Antenna with Fractal Defected Ground Structure

ABSTRACT

Microstrip patch antenna compatible in size with fractal defected ground structure (FDGS) has been designed and fabricated to enable successful implementation in modern communication systems. This attempt is dedicated to the wireless application of emergency management. In this paper, the presented structures are based on the coplanar waveguide (CPW) fed patch radiating element in conjunction with fractal geometry as a tuning stub. CPW feed is utilized to obtain the ultra-wideband (UWB) capacity of the presented antenna. Fractal structure as patch stub is employed to decrease the size of the antenna. The employed structure is tuned with the proficient Particle Swarm Optimization (PSO) technique for required frequency of emergency management. In light of investigating the band notching properties, slot of meander curve geometry and FDGSs is critically analyzed and discussed. Experimental tests on the manufactured prototype are conducted to examine the effectiveness of the antenna.
