Abstract: An outphasing antenna structure is provided that includes a first antenna feeder and a second antenna feeder. A high-PAPR signal is decomposed into a first constant-envelope signal that drives the first antenna feeder and into a second constant-envelope signal that drives the second antenna feeder. The pair of antenna feeders parasitically couple to an antenna that radiates the first and second constant-envelope signals that spatially combine in free space into the high-PAPR signal.
