Abstract

This paper presents the design, simulation, and optimization of a microstrip patch antenna optimized for Bluetooth applications (2.4–2.485 GHz). The antenna is designed on an FR-4 substrate (ε<sub>r</sub> = 4.3) with a compact structure suitable for IoT, wearable devices, and wireless communication systems. The proposed antenna is simulated using ANSYS HFSS (or CST Microwave Studio), achieving a return loss (S<sub>11</sub>) < -10 dB, impedance matching at 50 Ω, and a radiation efficiency > 80%. Parametric studies and optimization techniques (e.g., Particle Swarm Optimization) are employed to enhance performance. The simulation of this antenna was done by advanced design system (ADS-A gillnet) software.

Keywords: Microstrip antenna Bluetooth FR-4 HFSS PSO S<sub>11</sub> radiation pattern
