Abstract
An antenna array is provided, which may include a connection portion and a plurality of antenna units. The antenna units may be disposed on the two sides of the connection portion respectively. The proximal end of each of the antenna units may be connected to the connection portion and the distal end of one or more of the antenna units may be grounded. The length of each of the antenna units may be less than or equal to ¼ wavelength of the operating frequency of the antenna array, and the distance between any two adjacent antenna units may be less than or equal to ½ wavelength of the operating frequency of the antenna array.
Claims26
An antenna array, comprising:
- a connection portion;
- and
- a plurality of antenna units, disposed on two sides of the connection portion respectively;
- wherein a proximal end of each of the antenna units is connected to the connection portion and a distal end of one or more of the antenna units is grounded, a length of each of the antenna units is less than or equal to ¼ wavelength of an operating frequency of the antenna array and a distance between any two adjacent antenna units is less than or equal to ½ wavelength of the operating frequency of the antenna array.
A collision avoidance radar, comprising:
- a plurality of antenna arrays, wherein a distance between any two adjacent antenna arrays is less than or equal to ¾ wavelength of an operating frequency of the antenna arrays, and each of the antenna arrays comprises:
