Embodiment

[0025] Please refer to figure 1 , the present embodiment is a double-fed circularly polarized millimeter-wave array antenna system 100, which includes a substrate 1, a millimeter-wave array antenna 2 disposed on the substrate 1, and a first feeding unit 3 communicating with the millimeter-wave array antenna 2 with the second feed unit 4.

[0026] The millimeter-wave array antenna 2 includes several rectangular metal patches 21 distributed in a square array, and the rectangular metal patches 21 are connected through strip-shaped metal strips 22 .

[0027] The side length of the rectangular metal patch 21 is 1-4mm. Specifically, when it is necessary to design a 28-60GHZ millimeter-wave band antenna, the optimal choice of the side length of the rectangular metal patch 21 is 3-4mm, which can ensure that the unit The radiation resonance frequency generated by the rectangular metal patch 21 is in the corresponding millimeter wave band; when it is necessary to design a millimeter wa...

Abstract

The invention discloses a double-feed type circularly polarized millimeter wave array antenna system which comprises a substrate, a millimeter wave array antenna arranged on the substrate and a first feeding unit and a second feeding unit connected with the millimeter wave array antenna, wherein the millimeter wave array antenna comprises a plurality of rectangular metallic pasters in square array distribution, the rectangular metallic pasters are connected through bar-shaped metallic strips, and the first feeding unit and the second feeding unit are positioned on the adjacent edges of the millimeter wave array antenna and are mutually perpendicular to each other. The double-feed type circularly polarized millimeter wave array antenna system can radiate circular polarized wave and electromagnetic wave, generates good wave beam forming, improves transmit-receive efficiency, and reduces polarization loss.

Description

【Technical field】 [0001] The invention belongs to the technical field of communication, in particular to a double-fed circularly polarized millimeter-wave array antenna system. 【Background technique】 [0002] Electromagnetic waves with a wavelength of 1 to 10 millimeters are called millimeter waves. They are located in the wavelength range where microwaves and far-infrared waves overlap. Therefore, they have the characteristics of both spectrums and are the main frequency band for next-generation communications. The millimeter wave array antenna is a planar or three-dimensional antenna array realized by equal amplitude and equal means. [0003] As the next stage of technology and standard development in the field of mobile communication, the fifth generation mobile communication (5G) system has gradually entered people's field of vision. In recent years, 5G technology has attracted a lot of attention and entered the substantive research stage. Millimeter wave communication...
