Variable capacitive antenna loading for embedded RFID sensors Gonzalez, Giselle Jofre Roca, Lluís Romeu Robert, Jordi Cairó Molins, Josep Ignasi Universitat Politècnica de Catalunya.

ANTENNALAB - Grup d'Antenes i Sistemes Radio Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Radiocomunicació i exploració electromagnètica::Antenes i agrupacions d'antenes Microwave antennas Folded dipole Self-adaptive Relative permittivity Dielectric constant Ultra wide band RFID Antenes de microones In this paper, a self-adaptive folded dipole antenna to work embedded in media with changing physical and chemical properties for RFID applications is proposed. Self-adaptability is provided by taking advantage of the dual-mode behaviour of the folded dipole antenna where variable capacitance diodes are strategically placed to compensate for the change produced in the electromagnetic properties of the embedding medium. The presented antenna has been optimized at 868MHz. Peer Reviewed Postprint (published version) 2019 Conference report Gonzalez, G. [et al.].
