Impact of Feeding Methods on Patch Antenna Radiation Properties: Design and Analysis

Microstrip rectangular patch antennas are gaining popularity among antenna designers due to their appealing features, which include minimal size, small weight, and ease of manufacturing. But they additionally have certain disadvantages, such as low bandwidth and poor gain. With careful antenna design, these disadvantages can be somewhat mitigated. Numerous factors affect an antenna's radiating capabilities, but for this project, we are focusing on the electricity feeding the antenna because it is crucial. Three distinct feed techniques are being examined here, and their impact on radiating properties was investigated by contrasting all of the antenna parameters to one another.FR4's dielectric constant material is 4.4, its thickness is 1.6 mm, which is used to make the 2.4 GHz antenna. Ansoff HFSS version 13 was utilized in the design. Results are shown for return loss, gain, VSWR, and impedance.
