Abstract: An antenna structure, a radar, and a terminal may be applied to the field of millimeter-wave radars and can extend a 3 dB bandwidth of the antenna structure. The antenna structure includes: A main feeder and at least one patch unit group, where the at least one patch unit group is connected in series to the main feeder in a length direction of the main feeder, and each of the at least one patch unit group includes at least two patch units disposed in a V-shaped structure. Each patch unit group is connected in series to the main feeder through the two patch units that are disposed in the V-shaped structure and that are in each patch unit group.

Abstract: A transfer structure includes a circuit board that includes a first metal layer, a second metal layer, and a dielectric layer. The dielectric layer is located between the first metal layer and the second metal layer. The first metal layer includes a radiation portion and a microstrip that is coupled to one end of the radiation portion. The second metal layer is grounded. The radiation portion is provided with an opening to enable the radiation portion to form at least two resonance frequencies such that the operating bandwidth of the transfer structure can be extended.
