Abstract

This disclosure provides systems methods and apparatus for tuning a transmit antenna for operation in a plurality of frequency bands. In one aspect a transmitting antenna system is provided. The transmitting antenna system includes an active transmit antenna and a tunable passive antenna. The active antenna is configured to transmit a field over a plurality of operating frequencies. The passive antenna is configured to transmit a field over at least two frequencies of the plurality of operating frequencies. In one aspect the tunable passive antenna includes a network of a plurality of reactive elements. In another aspect the plurality of operating frequencies is selected from a set including a charging frequency an NFC frequency and a communication frequency.
