Web15°. The following sections explore the potential to use multiple-beam, wide-scanning antennas based on spherical lenses, and quantify the CIR values which could be expected. PROPERTIES OF SPHERICAL LENS ANTENNAS. In the context of HAPs communications, the very useful property of antennas using spherical lenses is their ability to WebJan 25, 2024 · 14 GHz holographic beamforming antenna made using metamaterials. These metamaterials antennas can be produced to operate between 1 and 70 GHz and produce highly-focused beams. (Image: Pivotal) Holographic antennas are expected to operate from about 500MHz to 60GHz. Signals can travel further with higher gain using holographic …
