Abstract

The invention belongs to the technical field of communication, and in particular relates to a folded planar Luneberg lens based on PCB technology and a manufacturing method. It includes an input terminal, an output terminal and a lens part; the lens part is composed of a complete Lunberg lens folded in half; the Lunberg lens folded in half is divided into two parts, which are respectively the first part and the second part; the first part and the The second part is composed of several metal layers and dielectric layers; the dielectric layer is a dielectric substrate; the dielectric substrate is provided with air through holes; there are multiple groups of air through holes on each dielectric substrate, and each group of air The inner diameters of the through holes are equal in size and distributed on concentric semicircular arcs; all the air through holes diffuse from the inside to the outside in a concentric semicircular structure, and the inner diameters of the air through holes increase sequentially from the inside to the outside. The multi-layer structure is used to fold the planar Lunberg lens, reducing the lens area to 1 / 2 of the original, and this Lunberg lens is based on the hole structure, which can be realized by PCB technology, reducing the cost.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a folded planar Luneberg lens based on PCB technology and a manufacturing method. Background technique [0002] Beamforming networks are passive circuits commonly used in modern wireless communication networks to control multiple beamforming and switching of antennas. For example, in satellite communication, it is necessary to receive the electromagnetic wave signal emitted by the satellite through the antenna, but as the receiving position changes, it is often necessary to adjust the main lobe direction of the antenna to align with the signal direction to achieve maximum signal reception. The multi-beam antenna provides a low-cost, high-efficiency beam switching method. Among them, the Lunberg lens is a commonly used beam forming network, which is used to excite the antenna array and realize the multi-beam antenna. [0003] Lunberg lenses in the prior art oft...
