AI Technical Summary
Existing planar antennas on mobile platforms suffer from reduced gain at low elevation angles, leading to data rate reduction or loss of connection with satellites, and existing solutions like metamaterials, variable-thickness radomes, and metasurface radomes are either immature, complex, or expensive.
A radome equipped with a diffractive structure at its periphery, functioning as a diffraction grating, deflects grazing electromagnetic waves to increase their elevation angle without significantly affecting higher-angle waves, using dielectric materials and 3D printing.
Enhances antenna gain at low elevation angles by deflecting electromagnetic waves, maintaining performance at higher angles with minimal distortion, offering a cost-effective and simple solution.
