Abstract
An antenna for a backscatter-based RFID transponder is provided that has an integrated receive circuit having a capacitive input impedance for receiving a radio signal spectrally located in an operating frequency range. The antenna includes two antenna branches that extend outward from a connecting region in which the antenna branches can be connected to the integrated receive circuit, and a yoke-shaped first trace segment that is designed to connect the two antenna branches together. Each antenna branch can have a U-shaped second trace segment connected to the connecting region, and a U-shaped third trace segment connected to the second trace segment and extending parallel to the second trace segment. The invention further relates to a backscatter-based RFID transponder with such an antenna.
