Abstract

The microstrip patch antenna has been developed and analyzed to meet the increasing demand for cost-effective, low-profile antennas suitable for various wireless applications, such as mobile phones and communication devices. To improve performance, the proposed design integrates a cut-slot structure and an inset feed technique. The proposed antenna design uses a cotton, with a dielectric constant of 1.61 and a loss tangent of 0.01, as the substrate material, offering a low dielectric constant to minimize return loss. Simulations, conducted using CST (Computer Simulation Technology) software, demonstrate a dual-frequency operation at 1.76 GHz and 3.42 GHz, suitable for targeted S-band applications. The final antenna structure achieves a gain enhancement of 5.43 dBi, indicating a significant improvement in performance.
