Abstract
The present subject matter relates to systems, devices, and methods for adaptively tuning antenna elements and/or associated filter elements to support multiple frequency bands. For example, a tunable filter having an input node and an output node can be selectively tunable to define one or more pass bands associated with one or more first signal bands and one or more reject bands associated with one or more second signal bands. The tunable filter can be configured to pass signals having frequencies within the first signal bands between the input node and the output node and to block signals having frequencies within the second signal bands. Furthermore, the tunable filter can be configured to selectively tune the pass bands to have a minimum pass band insertion loss at any of a variety of frequencies, including frequencies that are greater than and less than frequencies within the reject bands.
