By
Progress In Electromagnetics Research C, Vol. 173, 331-343, 2026
Abstract
This paper introduces an ultra-miniaturized, reconfigurable antenna for wireless communication applications. The suggested reconfigurable antenna is fabricated on an FR4-epoxy substrate (20 × 20 × 1.6 mm³, ε!= 4.4), and it provides a miniature factor 79% which is an outstanding value. Frequency reconfiguration can be achieved using two PIN diodes, which make the proposed antenna capable of working in various frequencies, including 5G/6G, WLAN, HiperLAN, V2X, WiMAX, Wi-Fi 6E/7/8, and S/C/X/Ku bands. With the analysis performed by CST Studio Suite, the proposed antenna shows outstanding quantitative results without any sacrifice in its size, cost, or complexity. In this context, the antenna shows dual-band impedance bandwidths of 1.36 GHz and 6.4 GHz. Additionally, it has 2 dBi of peak gain and 79% high radiation efficiency.
