Abstract
The present subject matter relates to filtering antenna devices, systems, and methods in which a tunable antenna having one or more first variable impedance element is configured to selectively vary an impedance at a signal path output and a tunable filter is in communication between the signal path output of the tunable antenna and a signal processing chain. The tunable filter can have one or more second variable impedance element configured to provide a frequency-selective filtering response between the signal path output and the signal processing chain. A controller in communication with both the tunable antenna and the tunable filter can be configured for selectively tuning an impedance value of one or more of the one or more first variable impedance element or the one or more second variable impedance element.
