Abstract: An antenna system for transducing radio-frequency energy includes: a first antenna sub-system comprising a plurality of radiators and a ground conductor, each of the plurality of radiators being sized and shaped to transduce millimeter-wave energy between first wireless signals and first electrical current signals; and a second antenna sub-system comprising a first radiator configured to transduce sub-6 GHz energy between second wireless signals and second electrical current signals, wherein the first radiator comprises the ground conductor.

Abstract: A wireless communication device includes: a first antenna configured to provide a first gain pattern at a millimeter-wave radio frequency and having a first boresight direction; a second antenna configured to provide a second gain pattern at the millimeter-wave radio frequency and having a second boresight direction that is different from the first boresight direction; and an electrically-conductive device; where the first antenna, in combination with the electrically-conductive device, is configured to provide a third gain pattern that has a first gain differential relative to the second gain pattern that is greater than a second gain differential between the first gain pattern and the second gain pattern over a range of angles relative to the wireless communication device.

Abstract: A method of using an antenna system, comprising a transducer that is configured to transduce between wireless signals and wired signals and that is disposed between a ground conductor and a frequency selective surface, includes: providing constructive interference between a first signal of a first frequency and a reflected first signal comprising a reflection of a portion of the first signal by the frequency selective surface and the ground conductor; and providing constructive interference between a second signal of a second frequency, different from the first frequency, and a reflected second signal comprising a reflection of a portion of the second signal by the frequency selective surface and the ground conductor.
