Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Such as Figure 1~Figure 6 As shown, the novel wide-angle high-gain coverage security radar antenna provided by the present invention includes a first dielectric substrate 1 and a second dielectric substrate 2. The first dielectric substrate 1 is manufactured by a selective electroplating process. A Rotman lens 10 is printed on the lower surface of the dielectric substrate 1, and 11 beam excitation ports 101 are printed on the beam profile of the Rotman lens 10, and each beam exci...

Abstract

The invention discloses a novel wide-angle high-gain coverage security and protection radar antenna used in the security and protection field. The antenna comprises a first dielectric substrate; a Rotman lens which is arranged on the lower surface of the first dielectric substrate; a second dielectric substrate; patch antenna arrays which are arranged on the upper surface of the second dielectricsubstrate in parallel; a metal bottom plate which is arranged between the first dielectric substrate and the second dielectric substrate. Due to the fact that the improved Rotman lens is combined withan unequal power division network for feeding, the broadband miniaturization of the feeding network is achieved. Through the combination of the feed network and the patch antenna array, the characteristics of wide-angle multi-beam coverage, the high gain and low sidelobe of the security radar antenna are realized at the same time, and the technical problems of large scale and small scanning angleof a traditional multi-beam radar antenna feed structure are solved.

Description

technical field [0001] The invention belongs to the technical field of radar, in particular to a novel wide-angle high-gain coverage security radar antenna used in the field of security. Background technique [0002] In the security field, security radars are required to meet the characteristics of wide-angle coverage and high-gain beams. A multi-beam antenna can generate multiple beams with different directions through the same radiation aperture. In many radar equipment, an array antenna with a microwave lens as a feed network is often used to obtain high-gain beam and wide-angle coverage characteristics. . [0003] Traditional multi-beam antennas based on Rotman lenses usually require larger lens sizes. If the parallel power division network is used, it also needs a large space, and the insertion loss is relatively large; if the series feeding method is used, the working bandwidth is limited. Therefore, a wide-angle high-gain coverage security radar antenna with a min...
