Embodiment Construction

[0100] The technical solution in this application will be described below with reference to the accompanying drawings.

[0101] figure 2 A schematic structural diagram of the antenna structure 100 provided by the embodiment of the present application is shown. The antenna structure 100 may include a main feeder 110 and at least one patch unit group, such as figure 2 121 to 12N are tile unit groups 121 to 12N, where N is an integer greater than 1. The patch unit group 121-12N are connected in series to the main feeder 110 along the length direction of the main feeder 110, wherein each patch unit group in the patch unit group 121-12N is at least Including two patch units arranged in a V-shaped structure, such as figure 2 It is shown that the patching unit group 121 includes a patching unit 131 and a patching unit 132 arranged in a V-shaped structure, and each patching unit group passes through two patching unit groups arranged in a V-shaped structure. A patch unit is conn...

Abstract

The invention provides an antenna structure, a radar and a terminal, which can be applied to the field of millimeter wave radars and can expand the 3dB bandwidth of the antenna structure. The antenna structure (100) comprises a main feeder line (110) and at least one patch unit group (121-12N), the at least one patch unit group (121-12N) is connected in series to the main feeder line (110) along the length direction of the main feeder line (110), and each of the at least one patch unit group (121-12N) at least comprises two patch units (131, 132) arranged in a V-shaped structure, each patch unit group (121-12N) is connected in series with the main feeder line (110) through two patch units (131, 132) arranged in a V-shaped structure on each patch unit group.

Description

technical field [0001] The present application relates to the field of sensor technology, and more particularly, to antenna structures, radars and terminals in the field of sensor technology. Background technique [0002] With the development of society and the advancement of science and technology, smart cars are gradually entering people's daily lives. Sensors play a very important role in the unmanned and intelligent driving of smart cars. The sensor can be millimeter-wave radar, laser radar, ultrasonic radar, camera, etc. For example, the 77GHz millimeter-wave radar, as a key sensor for unmanned driving technology, has the characteristics of short wavelength and small equipment size. No matter in terms of detection accuracy, detection distance or equipment integration, 77GHz millimeter-wave radar has irreplaceable advantages. [0003] From the perspective of radar detection scenarios and implementation functions, the antenna used by the radar is required to have the c...
