Problems solved by technology

Although the lens antenna is simple in design and excellent in performance, its inherent narrowband characteristics often limit its application in the field of broadband communication
The narrow-band limitation of the lens antenna is mainly caused by two points: one is the narrow-band characteristics of the lens unit; the other is the different spatial phase delays caused by the different spatial paths from the feed source to each unit on the lens aperture surface

Abstract

The invention discloses a planar broadband lens antenna based on a transceiver structure. It can be used in satellite communication, radar detection and other fields. The lens antenna combines the principle of the planar ultra-broadband strong coupling antenna unit with the design of the lens unit, and solves the narrow-band problem of the traditional lens antenna. The designed planar broadband lens unit can be regarded as three parts: the upper part of the broadband antenna unit, the stripline structure that transmits electromagnetic energy and achieves linear phase shift, and the lower part of the broadband antenna unit that is symmetrical to the upper part. The antenna can be realized through mature PCB processing technology. Compared with the traditional lens antenna, the planar broadband lens antenna based on the transceiving structure described in the present invention can maintain good radiation performance in a wider working bandwidth.

Description

technical field [0001] The invention belongs to the field of radar technology and wireless communication technology, and in particular relates to a broadband lens antenna based on a transceiver structural unit, in particular to a planar, wide-band, high-gain antenna, suitable for radar and wireless communication systems such as microwaves and millimeter waves. Background technique [0002] In recent years, lens antennas have attracted much attention in the field of communication and are widely used in radar and wireless communication systems. The lens antenna combines optical theory and antenna array synthesis technology, and has the advantages of low profile, low manufacturing cost, high gain, high radiation efficiency, etc. The basic principle is to convert the spherical wave radiated by the feed source placed at the equivalent focal point into Plane wave, focus the beam to achieve high gain, or optimize the amplitude and phase distribution of the elements on the lens aper...
