AI Technical Summary
Technical Problem
Existing RF antennas with spherical lenses suffer from significant side-lobe energy wastage due to spherical aberration, which is difficult and costly to mitigate using current methods that either require increased physical space, complex geometric patterns, or reduce antenna aperture efficiency.
Method used
Incorporating a plug with optically active materials or a single unitary material in the optical path of the RF antenna, designed to refract and reflect RF energy towards the center of the spherical lens, reducing spherical aberration and side-lobe energy.
Benefits of technology
The plug effectively minimizes side-lobe energy by focusing RF energy more narrowly, reducing spherical aberration and improving radiation efficiency while maintaining a compact design.
