Embodiment Construction

[0023] In view of the fact that the antenna array in the existing 5G millimeter-wave communication technology is difficult to meet the size requirements and the phase-consistent requirements of the signals transmitted by each array element, this invention proposes a millimeter-wave antenna array element based on the idea of ​​vertical integration. The SIW filter and the gradient fin antenna are integrated by sharing the dielectric substrate, which has the advantages of compact structure and small footprint, and more importantly, it can ensure the phase and amplitude of the signal transmitted by each element in the antenna array Basically the same.

[0024] Substrate-integrated waveguide is a new form of microwave transmission line, which uses metal through holes to realize the field propagation mode of waveguide on the dielectric substrate, which takes into account the advantages of traditional waveguide and microstrip transmission line, and can realize high-performance microwa...

Abstract

The invention discloses a millimeter wave antenna array element which comprises two vertical platy radiation units. The platy radiation units are mutually orthogonal and used for radiating vertical polarization direction signals and horizontal polarization direction signals. The platy radiation units comprise lower substrate integrated waveguide (called SIW for short) filters and upper gradient fin line antennas, and the lower substrate integrated waveguide filters and the upper gradient fin line antennas share the same dielectric substrate. The invention further discloses a millimeter wave antenna array and a millimeter wave communication device. Radiation components and the filters are vertically integrated into a whole, the millimeter wave antenna array element has the advantage of compact structure, and more importantly, phases and amplitudes of signals transmitted by each array element in the antenna array can be kept basically the same.

Description

technical field [0001] The invention relates to the technical field of microwave communication, in particular to a millimeter wave antenna array element. Background technique [0002] 5G millimeter wave frequency band communication is the most cutting-edge communication technology and the most important research direction in the field of communication in the near future. All major communication companies in the world have carried out related research work. At present, the 5G millimeter wave communication systems of various companies use MIMO and phased array technology, most of which use array antennas with 8*8 or 16*16 radiation elements, including waveguide slot array antenna arrays and patch arrays. antenna array etc. Some schemes adopt two-dimensional scanning schemes, and some adopt one-dimensional scanning schemes. [0003] No matter which form is used, the local oscillator radiation must be suppressed to meet the international radio radiation standards in order to ...
