“…The dielectric permittivity ranges from 1 to 84.5. Our results agreed with the previous theoretical analysis [10] and showed the expected behavior. The coating was an effective buffer that minimized the impact of the changing environment on antenna performance.…”

“…Once the final design was chosen, we added the coating and readjusted the antenna size in accordance with the change in permittivity. The second stage was related to the coating design, for which we considered previous theoretical work [10]. Those authors showed how proper packaging can minimize changes in the antenna reactance due to differences in the surrounding dielectric medium.…”

“…Packaging antennas is a potential way to resolve these issues that has already been proposed in previous studies [10]. Dielectric encapsulation to guarantee stable antenna impedance when immersed in a dielectric medium was validated through numerical simulations; and packaging can be designed to minimize changes in antenna reactance.…”

This paper presents the design, manufacture and characterization of a novel 3D passive UHF-RFID tag for embedded applications. The prototype is fabricated using additive manufacturing techniques: 3D printing and copper electroplating. The design, manufacturing process and measurement setup are presented and discussed in detail. We propose a biconical antenna design with spiral strips embedded in the cones to provide compactness without breaking the symmetry of the component and to improve bandwidth. The antenna is matched to a commercial UHF-RFID integrated circuit. We incorporate a packaging design that consists of a dielectric coating, to provide proper operation in different media or surrounding environments with changing electromagnetic properties. The good agreement between experimental results and Finite Element Method simulations allows us to validate the whole process. Finally, a compact capsuletype RFID tag is proposed and its performance in different media is reported.
