Abstract

The invention discloses an array antenna subarray, an array antenna module and an array antenna. At least two unit antennas are arranged on the surface of a dielectric substrate, the at least two unitantennas surround a first center of the surface of the dielectric substrate, and the rotation angle difference between adjacent unit antennas is 360 degrees / N. Meanwhile, each unit antenna is the same, and the distance between each antenna unit and the first center is the same. The antenna subarray arranged by adopting the above mode has very compact spatial arrangement after being assembled intoa phased array antenna, and a better circular polarization function can be achieved. In addition, metal vias can also be arranged around each unit antenna and between two adjacent unit antennas, so that the isolation of the whole phased array antenna is improved on the basis of improving the isolation between the unit antennas, thereby having the technical effects of improving the overall electrical performance of the phased array antenna and improving the wide-angle scanning ability of the phased array antenna.

Description

technical field [0001] The invention relates to the field of microwave and millimeter wave array antennas, in particular to an array antenna sub-array, an array antenna module and an array antenna. Background technique [0002] Microstrip patch antennas are increasingly being widely used in the field of communication because of their advantages of small size, light weight, low profile, and easy conformality with various carriers. Splicing microstrip patch antennas according to a specific layout can become a phase-controlled Array array antenna, phased array antenna using electronic scanning technology has the characteristics of fast scanning speed and high beam pointing accuracy. However, the antenna performance obtained by the current phased array layout is often not optimal. When the phased array antenna is used in an environment with limited space or conditions, it is often due to the difference between the antenna array used to receive signals and the antenna array used ...
