Abstract
In this paper, a novel approach in Microstrip Patch Antenna analysis and design has been introduced. Here, a low-profile fractal microstrip antenna has been presented. ‘Sierpinski Triangular’ fractal geometry has been applied in the designing the antenna. Evolutionary Particle Swarm Optimization technique has been utilized for optimizing the design parameters. Triangular slots have been etched in the ground plane, repeated in the subsequent iterative stages. An inverted triangular patch has been placed on top of almost 1.00 mm thick Roger 4350 substrate having an electrical permittivity of 3.48 and loss tangent of 0.004. The antenna resonating frequency is 3.5 GHz with an impedance bandwidth of 700 MHz. The antenna finds its application in 3.5 GHz WiMAX band with a maximum gain of 3.34 dBi and return loss factor of 24 dB at the resonant frequency, which is reasonably better than conventional microstrip patches.
