Abstract

See full text

An antenna circuit is having an impedance circuit which can cancel signal leakage from the input port into the isolation port of a directional coupler. The antenna circuit further comprises a second impedance circuit for optimizing power transfer from the input port to the output port of the directional coupler. Furthermore, the antenna is tunable in order to maximize the reception strength of the antenna. The antenna circuit provides at once the possibility of tuning the antenna strength, optimizing the power transmission and reducing signal jamming by cancelling signal leakage. The antenna finds use as an effective and miniature RFID antenna.
