Direct-written printed dual-polarized meshed antenna for chipless RFID sensing
Direct-written printed dual-polarized meshed antenna for chipless RFID sensing
This paper presents a dual-polarized coplanar waveguide (CPW) monopole antenna, fabricated using additive manufacturing on a flexible substrate for chipless RFID tags. The proposed antenna is based on a dual-port broadband disc monopole with a CPW feed and a notched ground plane for mutual coupling suppression, occupying over 50% less area compared to a dual-antenna tag. The antenna is meshed achieving a 90% transparency and is fabricated using dispenser printing on a flexible polyimide substrate. Through a ground plane notch and using meshed conductors, the antenna’s total efficiency is improved by 30% over a standard dual-port disc. The antenna maintains a simulated and measured S11 bandwidth form 1.4 to 2.55 GHz. With over 60% and up to 75% radiation efficiency while being 90% optically-transparent, the antenna is suitable for chipless RFID applications in the sub-6 GHz UHF spectrum.

Abstract
This paper presents a dual-polarized coplanar waveguide (CPW) monopole antenna, fabricated using additive manufacturing on a flexible substrate for chipless RFID tags. The proposed antenna is based on a dual-port broadband disc monopole with a CPW feed and a notched ground plane for mutual coupling suppression, occupying over 50% less area compared to a dual-antenna tag. The antenna is meshed achieving a 90% transparency and is fabricated using dispenser printing on a flexible polyimide substrate. Through a ground plane notch and using meshed conductors, the antenna’s total efficiency is improved by 30% over a standard dual-port disc. The antenna maintains a simulated and measured S11 bandwidth form 1.4 to 2.55 GHz. With over 60% and up to 75% radiation efficiency while being 90% optically-transparent, the antenna is suitable for chipless RFID applications in the sub-6 GHz UHF spectrum.
