Embodiment Construction

[0050] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, only a part of the embodiments of the present invention, not all the embodiments, and are not intended to limit the present invention.

[0051] The inventors found that most of the feed sources of current lens antennas use fixed single beams, and a few feed sources use multi-beams, but they are all one-dimensional linear arrays, so that the water space that the antenna can cover is very limited. However, the collection of hydrological information and the monitoring of the state of the water often require large space and all-round data. Using the existing lens antenna to complete the data collection and state monitoring...

Abstract

The invention discloses a lens antenna based on the 3D printing technology. The lens antenna comprises a hyperbolic lens, a support body and a feed source array. The support body and the hyperbolic lens are made of liquid resin by using the stereoscopic light curing molding 3D printing technology, the feed source array is integrally formed by metal powder by using the selective laser melting 3D printing technology, the feed source array is formed by combining a plurality of feed resources in an orthogonal form, and each of the multiple feed resources comprises a square flange, a rectangle to circle waveguide and a round table. According to the lens antenna based on the 3D printing technology of the invention, a feed source form of a multi-beam two-dimensional plane array is achieved whilethe gains of an E plane and an H plane of the lens antenna are ensured, the processes of hydrological data collection and state monitoring is simplified when the antenna is applied to the hydrologicalfield, and the choices of antennas in the hydrological field are enriched.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a lens antenna based on 3D printing technology. Background technique [0002] Antennas are widely used in radio systems such as communications, broadcasting, television, radar, and navigation. They play the role of spreading radio waves and are an essential device for effectively radiating and receiving radio waves. [0003] In the field of hydrology, the acquisition of hydrological information and the monitoring of the state of the water area need to be carried out simultaneously on a large area of ​​water or multiple targets in the water from a distance. Therefore, the antenna is required not only to have a high gain, but also to cover a large area wide enough. [0004] Lens antennas are widely used in the field of hydrology due to their own characteristics and advantages. However, most of the current lens antenna feeds use fixed single beams, and a few feeds use multi-beams, but they...
