Abstract

The invention relates to a millimeter wave printed dipole antenna array radiating element and an array antenna. The millimeter wave printed dipole antenna array radiating element include a dielectricsubstrate, a feed strip line, and a dipole antenna. First, two dipole antennas are printed on the two surfaces of the dielectric substrate respectively so as to enhance the radiating and receiving capabilities of the dipole antennas. Secondly, because the projection of the feed strip line in the horizontal direction and the projection of a slot in the horizontal direction intersect each other, theslot is divided into two sections, the upper section of which is a series feed slot, and the lower section of which is a balance/unbalance conversion structure. The series feed slot moves the radiating arms of the dipole antennas upward to facilitate feeding. The balance/unbalance conversion structure improves the working frequency band of the dipole antennas such that the dipole antennas can operate in a wide frequency band. Thus, the millimeter wave printed dipole antenna array radiating element that is convenient for feeding and can operate in a wide frequency band is achieved, and is simple in structure and easy to machine.

Description

technical field [0001] The invention relates to the technical field of dipole antennas, in particular to a millimeter-wave printed dipole antenna array radiation unit and an array antenna. Background technique [0002] As an important part of modern communication systems, antennas mainly function to receive and transmit electromagnetic waves. With the development of communication technology, the performance requirements of communication systems for antennas are also increasing. At present, the conventional printed dipole antenna is to print the dipole antenna on a thin layer of dielectric substrate, which has the advantages of light weight, small size, easy integration into arrays, etc., and has good bandwidth characteristics and high pole Purity. Its structure is that on the dielectric substrate perpendicular to the metal reflector, a dipole antenna is printed on one side, and a matching feeder is printed on the other side, but its frequency band is narrow, and the size of...
