Abstract
Recent progress in microstrip antennas has improved their size and efficiency, particularly in mobile, satellite, and Wi-Max technologies. These enhancements are crucial for advancing wireless communication systems, benefiting applications like telemedicine and GPS technology. The chapter introduces a dual-band unit cell of frequency selective surface (FSS) resonating at 4 GHz and 5.5 GHz, using a combination of I-shaped and modified I-shaped metal strips for dual-band filtering. The research focuses on individual shape analyses and aims to contribute to the development of compact and efficient dual-band FSS designs. The research introduces a dual-band FSS unit cell resonating at 4 GHz and 5.5 GHz, combining I-shaped, H shaped, and modified I-shaped and H shaped metal strips for dual-band filtering. The proposed FSS design, with a 10x10 mm2 unit cell dimension and FR-4 dielectric, exhibits broad frequency band characteristics, aligning well with simulated and measured results.
