Compact Multi-Band Flexible Antenna for ISM, WLAN, Wi-Fi, and 5G sub-6-GHz Applications
Résumé
Design and analysis of a compact multi-band flexible antenna are presented here. The antenna is designed using the flexible substrate material Rogers 5880 and has a compact size of 18mm×18mm×0.254mm. The coplanar waveguide (CPW) fed radiator consists of a rectangular-shaped patch modified using a pair of rectangular slots to achieve the required bandwidth. Another smaller slot was etched in the radiator to achieve a lower resonance. The proposed design offers a multi-band functionality covering ISM, WLAN, Wi-Fi, and upper 5G sub-6-GHz bands.
