Design and Performance Analysis of Multiband Microstrip Antenna for Wireless Communication Applications

This study presents a multiband microstrip antenna designed and analyzed for wireless communication applications. The proposed antenna (Prop-Ant) is designed on a FR-4 substrate material. The Prop-Ant has dimensions of 37.5 × 46 × 1.6 mm3. 3D electromagnetic simulation software was used to design and analyze the antenna. The simulation results indicate that the antenna, with the specified dimensions, achieves a reflection coefficient of less than 10dB in the targeted frequency ranges. In the simulation, the Prop-Ant operates at resonant frequencies of 2.45GHz, 4.78GHz and 7.6GHz with bandwidths of approximately 46.12 % (2.09 GHz - 3.22 GHz), 45.18 % (3.75 GHz - 5.91 GHz) and 25.92 % (6.51 GHz - 8.48 GHz), respectively. The simulation results show that the Prop-Ant has peak gains of 2.27dBi, 3.63dBi and 4.28dBi at resonant frequencies of 2.45GHz, 4.78GHz and 7.6GHz, respectively. The Prop-Ant exhibits high gain, good efficiency and multiband performance, indicating that it can be used in wireless communication systems.
