Abstract
An antenna circuit includes a first antenna tuned to a first fundamental frequency and a second antenna tuned to a second fundamental frequency different from the first fundamental frequency. A first filter has a first terminal connected to the first antenna and attenuates the frequency components outside of a band defined by the first fundamental frequency or its harmonics. A second filter has a first terminal coupled to the second antenna and attenuates the frequency components outside of a band defined by the second fundamental frequency or its harmonics. A passive recombination element couples the second terminals of the two filters to a common terminal.
