摘要：A multi-frequency folded lens antenna structure includes a stack, and the stackincludes a polarization-dependent trans-reflector, a dielectric gap, and a multi-frequencytwist-reflector; wherein the polarization-dependent trans-reflector is configured to

transmit electromagnetic radiation of a first polarization incident from within the stackout of the stack and to reflect electromagnetic radiation of a second, different

polarization incident within the stack towards the multi-frequency twist-reflector, and themulti-frequency twist-reflector is configured to selectively change a polarization of thereflected electromagnetic radiation from the second polarization to substantially thefirst polarization and to direct the electromagnetic radiation of substantially the firstpolarization, within the stack, towards the polarization-dependent trans-reflector for atleast partial transmission out of the stack, wherein the multi-frequency twist-reflector isconfigured to selectively change the polarization for at least a first frequency band andfor at least a second frequency band, non-contiguous to the first frequency band.
