Power Pattern Synthesis of Time Modulated Circular Array Antenna Employing Optimization Algorithm

In this Research paper demonstrates the synthesis of Time Modulated Circular Antenna Array (TMCAA) radiation beam characteristics employing an evolutionary optimization method called Particle Swarm Optimization (PSO). The antenna radiation beam pattern of Far-Field is enhanced by reducing the side lobe level (SLL), most common and important param-eter of radiation pattern of antenna. By suppressing side lobe level, undesired signals and interfered signals in the common frequency band which is frequency reuse are reduced. It shows the performance and flexibility of the proposed technique for different elements 10, and 18. A reduced side lobe level is needful to overcome some noise in the working in common frequency a decreasing First Null Beam Width (FNBW) it helps the desire antenna to acquire the maximum directivity. The operation of TMCAA depends on rise time-fall time the present paper the in addition of beam pattern of antenna at the operating frequency as well as leadoff two harmonic frequencies are chosen in this case of TMCAA design. Optimization variables are gotten better radiation beam characteristics of TMCAA. The attained simulation results are validated in practical case known as high frequency structure simulator (HFSS) software platform.
