Patent abstract
Systems and methods for reducing the beamwidth of an antenna system are provided. An evanescent field generator generates an evanescent field representing a far field radio frequency (RF) signal received at the antenna system. A negative refractive index lens assembly focuses the evanescent field onto a focal plane. An RF detector assembly located in the focal plane detects the amplified evanescent field.
