The rapid growth of wireless communication systems has increased the demand for efficient and compact antenna designs capable of operating in the Industrial, Scientific, and Medical (ISM) frequency bands. Antennas play a crucial role in ensuring reliable data transmission in wireless routers and communication devices. This research work focuses on the design and simulation of a 2.5 GHz circular microstrip patch antenna for wireless router applications. The proposed antenna is designed using an FR-4 substrate with a dielectric constant of 4.4 and a thickness of 1.6 mm. The antenna structure is modelled and analysed using ANSYS HFSS (High Frequency Structure Simulator) to evaluate important parameters such as return loss (S11), Voltage Standing Wave Ratio (VSWR), and radiation characteristics. The results obtained from the simulation demonstrate good impedance matching and stable performance at the target frequency band. The proposed antenna design provides a low-cost, compact, and efficient solution suitable for wireless communication systems, particularly for wireless routers operating around the 2.5 GHz frequency band. The proposed design also ensures improved signal propagation and stable radiation performance for reliable wireless connectivity. Furthermore, the antenna structure can be easily fabricated and integrated into modern wireless communication devices.
