Abstract: There has been a significant amount of research conducted in recent times with the purpose of constructing and optimizing dual-band microstrip patch antennas, particularly for applications that include wireless communication technologies such as Wi-Fi and 5G. With the growing demand for high-speed wireless connectivity, antennas now play a critical role in electronic devices. A dual-band antenna, capable of resonating at two distinct frequencies, is the focus of this study. In this research work, a dual-band antenna is designed with a unique geometry optimized for compactness and performance. This antenna is configured to operate at two specific resonance frequencies, 2.4 GHz and 3.5 GHz. The design and simulation were carried out using the High Frequency Structure Simulator (HFSS) Student R2 version. The return losses at 2.4 GHz and 3.5 GHz are -27.1633 dB and -28.5333 dB, respectively, ensuring excellent impedance matching. The proposed antenna achieves a maximum gain of 4.7 dB, with the magnetic field oriented in the YZ plane and the electric field confined to the XZ plane, peaking in the Z direction. This design demonstrates its suitability for high-speed dual-band wireless communication applications.
