The invention discloses an antenna unit and an antenna module. The antenna unit comprises: an antenna layer which comprises an antenna body, a first microstrip line and a second microstrip line which are insulated from one another; and a feed layer which is located on one side of the antenna layer and comprises a first feed line and a second feed line which are coupled with the antenna body, wherein the first feed line and the second feed line are insulated. One end of the first microstrip line and one end of the first feeder line are electrically connected through a first conductive hole, and one end of the second microstrip line and one end of the second feeder line are electrically connected through a second conductive hole. The sum of the length of the first conductive hole between the first microstrip line and the first feeder line and the length of the first microstrip line, and the sum of the length of the second conductive hole between the second microstrip line and the second feeder line and the length of the second microstrip line are integral multiples of the half wavelength. According to the antenna unit provided by the invention, defects caused by back drilling can be avoided, and the processing cost can be reduced while the requirement of antenna performance is met.
Description
technical field [0001] The present application relates to the technical field of antennas, in particular to an antenna unit and an antenna module. Background technique [0002] In recent years, due to the rapid development of electronic space technology, the types and forms of antennas used in equipment are increasing, and the requirements for their performance are also increasing. For example, the current trend of antennas is towards miniaturization. [0003] The inventors of the present application found that the current millimeter-wave antennas have problems such as high cost and low processing efficiency. Contents of the invention [0004] The technical problem mainly solved by this application is to provide an antenna unit and an antenna module, which can not only avoid the defects caused by back drilling, but also reduce the processing cost while meeting the antenna performance requirements. [0005] In order to solve the above technical problems, a technical soluti...
