Design and Simulation of 2.45 GHz Microstrip Patch Antenna for S-Band Wireless Applications

In this research paper, discusses the examination, design, and analysis of a rectangular microstrip patch operating at a frequency of 2.45 GHz. The antenna is constructed using a lossy material called Rogers RT5880, with specific characteristics including a dielectric permittivity of 2.2, a thickness of 1.6 mm, and a loss tangent of 0.0001. To design and simulate the antenna, the researchers utilized Studio 2019, a software suite within the computer simulation technology field. Additionally, Origin Software was employed for various plot designs. The simulation results yielded several outcomes, including return loss, voltage standing wave ratio (VSWR), gain, directivity, bandwidth, and efficiency. These parameters were measured and found to have - 46.453 dBi, 1.0096, 5.202 dBi, 5.590 dBi, 54.5 MHz, and values, 93.05% respectively. The study's main objective is to reduce the return loss to a typical VSWR value close to 1. The researchers also aimed to enhance the antenna's gain, directivity, and efficiency.
