Parametric Optimization of Microstrip Patch Antenna Design for Enchanced Performance at 3.5 GHz Wireless Applications

This paper focuses on the parametric optimization of a microstrip patch antenna design for enhanced performance in 3.5 GHz wireless applications. Utilizing Polytetrafluoroethylene (PTFE) as the substrate material. The substrate, with a thickness of 1.6 mm and a relative permittivity, εr of 2.1, meticulous design considerations are employed to optimize antenna performance. Simulation conducted via Computer Simulation Technology (CST) Studio Suite software showcases a gain of 6.823 dBi at the antenna's resonant frequency of 3.5 GHz. Furthermore, the observed return loss, S

is −22.80 dB, with an impedance bandwidth characterized by return loss below −10 dB spanning from 3.47 GHz to 3.53 GHz. Notably, the VSWR value of 1.15 indicates efficient impedance matching. The integration of CST software in the simulation process enhances the precision and reliability of the results, providing valuable insights into the design and performance characteristics of microstrip patch antennas.
