Abstract
Antenna assemblies and corresponding modes of operation are provided where the first antenna assembly of the system is tuned to a first frequency band ν1 and the second antenna assembly of the antenna system is tuned to a second frequency band ν2. The ground plane of the first antenna assembly is configured as a frequency selective surface that is substantially reflective of radiation in the first frequency band and substantially transparent to radiation in the second frequency band. The second ground plane may also be configured as a frequency selective surface and may be reflective of radiation in the second frequency band. Any number of additional antenna arrays may be added so long as the outer arrays are transparent to the inner arrays.
