Abstract: A multi-frequency and multi-beam independent electrically adjustable antenna includes: a first electromagnetic lens, a second electromagnetic lens, a mounting plate, a reflecting plate, oscillator units, oscillator units, and phase shifters. The oscillator units have a higher operating frequency than the oscillator units. The first electromagnetic lens, the second electromagnetic lens, the reflecting plate and the mounting plate are fixed relative to each other. The oscillator units and the oscillator units are all mounted on a reflecting surface of the reflecting plate. The phase shifters are all mounted on the mounting plate. The present application is characterized by simple structure, scientific design, small size, flexible setting of beam direction and etc.

Abstract: The present disclosure provides a production method for a Luneburg lens, which can manufacture a Luneburg lens with stable indexes and high performance under the conditions of room temperature, normal pressure, and low cost. The production method includes the following steps: bonding first granular materials into a sphere by a bonding agent, so as to obtain a sphere core; spraying the bonding agent on the surface of the sphere core, placing the sphere core in a container containing second granular materials, and rolling the sphere core, so that the surface of the whole sphere core is bonded with the second granular materials until the thickness of the second granular particles reaches a preset range, and thus forming a dielectric layer coating the sphere core; and by analogy, preparing a predetermined number of dielectric layers, so as to obtain a target finished Luneburg lens.
