A wide-band frequency-selective surface for enhancing the performance of microstrip antenna
Published online by Cambridge University Press: 03 March 2025
Abstract
This work presents the design of a wide-band frequency-selective surface (FSS) with its analysis for the performance enhancement of a microstrip antenna. To demonstrate the concept, a dual-band microstrip antenna is also designed and combined with the proposed FSS to investigate its advantages and performance enhancement capabilities. The proposed FSS is designed for a frequency range of 3.5–6.5 GHz, whereas the designed antenna operates in dual frequency bands of 3.5 and 5 GHz. The combined effect of the antenna and FSS is investigated at 5 GHz for improving the gain of the antenna from 2.8 to 3.2 dBi. The outcome of the measured performance validates that the proposed surface has potential capability for enhancing the gain of an antenna for 5G, WLAN, and Wi-Fi communication.
