3D Antenna Assembly with Projected AMC and Applications Thereof

An antenna assembly comprises:

• a spiral antenna feed that includes:
• a substrate having a three-dimensional hyperbolic shaped region;
• a plurality of spiral antenna sections, wherein each spiral antenna section of the plurality of spiral antenna sections is supported by a corresponding section of the three-dimensional hyperbolic shaped region and conforms to the corresponding section of the three-dimensional hyperbolic shaped region such that, collectively, the plurality of spiral antenna sections has an overall shape approximating a three-dimensional hyperbolic shape;
• and
• a feed point coupled to a connection point of at least one of the plurality of spiral antenna sections;
• and
• a programmable circuit operable to produce a projected artificial magnetic conductor reflector dish that:
• reflects an inbound RF signal to the three-dimensional spiral antenna feed;
• and
• reflects an outbound RF signal transmitted by the three-dimensional spiral antenna feed.

A radio frequency (RF) front-end module comprises:

• an antenna assembly that includes:
• a hyperbolic shaped spiral antenna feed;
• and
• a programmable circuit operable to produce a projected artificial magnetic conductor reflector dish that:
• reflects an inbound RF signal to the hyperbolic shaped spiral antenna feed;
• and
• reflects an outbound RF signal transmitted by the hyperbolic shaped spiral antenna feed;
• a receive-transmit isolation module operably coupled to the antenna assembly, wherein the receive-transmit isolation module is operable to isolate the inbound RF signal and the outbound RF signal;
• and
• a tuning module operable to tune the receive-transmit isolation module.
