Reconfigurable Antenna Based CLRH Inclusions for 5G Wireless Networks

This paper describes a flexible and frequencyreconfigurable antenna with a unique structure that suppresses interference for multiple wireless applications. The antenna design is based on a square shape with etched slots and utilizes pin diodes to achieve frequency reconfigurability by connecting and disconnecting the stubs and the rectangular patch. The antenna is designed on a conformal substrate. It resonates at five different reconfigurable bands (1.4GHz, 2.1GHz, 2.3GHz, 2.5GHz, 4.6GHz, 5GHz, 5.6GHz, 6GHz) that are commonly used for 5G sub-6 GHz. Simulated results demonstrate excellent performance in impedance matching, controllable resonant bands, and high gain (>10 dBi). The antenna exhibits consistent radiation patterns and achieves an efficiency of over 88%. Additionally, conformal analysis indicates that the antenna maintains its performance in both flat and bending conditions, rendering it suitable for flexible electronics. Furthermore, the antenna is compared with state-of-the-art works in similar applications to demonstrate its potential across targeted band spectrums.
