Embodiment 1

[0038] see Figure 1-2 , the present invention provides an antenna system 100, including a system ground unit 1 and an antenna unit 2 coupled to each other.

[0039] The system ground unit 1 includes a substrate 11 and a system ground 13 laid on the surface of the substrate 11 .

[0040] The antenna unit 2 includes a support frame 21 , a monopole feeding pin 22 and a monopole radiator 23 .

[0041] In this implementation manner, the antenna unit is a millimeter wave antenna, and its operating frequency range is 26.5 GHz˜29.5 GHz.

[0042] The supporting frame 21 has a receiving space, which is a columnar structure with one end open and one end closed, such as a rectangular column. An open end cover of the support frame 21 is fixed to the system unit 1 .

[0043] In this embodiment, the size of the supporting frame 21 is 2.8mm*2.8mm*2mm, but of course it is not limited thereto.

[0044] The support frame 21 is specifically made of low temperature co-fired ceramics (Low Temp...

Embodiment 2

[0060] Please combine Figure 5 As shown, this embodiment is basically the same as Embodiment 1, except that the antenna system 500 includes several antenna units 52 arranged in a linear array, for example, includes at least three antenna units 52 arranged in a linear array Except for the system unit 51, other structures are the same as those in Embodiment 1, and will not be repeated here.

[0061] This embodiment is described by taking three antenna units 52 as an example, and the three antenna units 52 form a phased array antenna.

[0062] Please combine Figure 6-7 as shown, Figure 6 is the rectangular coordinate diagram and polar coordinate diagram of the gain of the antenna system at 28GHz, where Figure 6 a is the rectangular coordinate diagram on the surface of Phi=0°, Figure 6 b is the polar coordinate diagram on the Phi=0° plane.

[0063] Figure 6 The antenna gain at different scanning angles is shown, and it can be seen that the main lobe of the antenna beam...

Embodiment 3

[0066] Please combine Figure 8 As shown, this embodiment is basically the same as Embodiment 1, except that the antenna system 800 includes several antenna units 82 arranged in a planar array, such as including at least four antenna units 82 arranged in a rectangular array on the unit 81 of the system. Except for this, other structures are the same as those in Embodiment 1, and will not be repeated here.

[0067] This embodiment is described by taking four antenna units 82 as an example, and the four antenna units 82 form a rectangular phased array antenna, that is, arranged in a 2*2 matrix. The antenna units 82 arranged in an array can perform beam forming and beam steering at different angles on any plane, that is, the beam steering is almost omnidirectional.

[0068] Please combine Figure 9-13 as shown, Figure 9 is the gain rectangular coordinate diagram and polar coordinate diagram of the antenna system 800 at a plane Phi=0° and a frequency of 28 GHz, Figure 9 a i...

Abstract

The present invention provides an antenna system, which includes a system ground unit and an antenna unit coupled to each other. The antenna unit includes a support frame with a storage space covered and fixed on the system ground unit, and a unit set in the storage space. pole feed pin and a monopole radiator printed on the support frame; the system ground unit includes a substrate and a system ground laid on the surface of the substrate; the monopole feed pin abuts against the substrate and A coupling gap is formed with the system ground, the monopole radiator is spaced apart from the system ground and is electrically connected to the end of the monopole feed pin away from the system ground unit, and is in a spiral structure away from the system ground. Extend in the direction of the unit of the system described above. The invention also provides a communication terminal. Compared with related technologies, the antenna system and the communication terminal of the present invention have high spatial coverage efficiency and stable signals.

Description

technical field [0001] The invention relates to an antenna, in particular to an antenna system and a communication terminal used in the field of communication electronic products. Background technique [0002] With the development of mobile communication technology, mobile phones, PADs, notebook computers, etc. have gradually become indispensable electronic products in daily life, and these electronic products have been updated to electronic communication products that add antenna systems to enable communication functions. [0003] As the research and development focus of the global industry, 5G has three main application scenarios: enhanced mobile broadband, large-scale machine communication, and high-reliability and low-latency communication. These three application scenarios correspond to different key indicators. In the enhanced mobile bandwidth scenario, the user peak speed is 20Gbps, and the minimum user experience speed is 100Mbps. The unique high carrier frequency a...
