Description

Technical Field

[0001] This utility model relates to the field of antenna manufacturing technology, specifically to an integrated antenna and an automobile. Background Technology

[0002] With the rapid development of mobile communication technology, modern wireless devices (such as smartphones, IoT terminals, and smart vehicle systems) are increasingly demanding multi-band coverage, high-speed data transmission, and multi-antenna collaborative operation capabilities. In particular, the widespread application of multiple-input multiple-output (MIMO) technology requires the integration of multiple antenna elements within a limited device space to support high-frequency, multi-channel communication, while also ensuring antenna isolation and anti-interference performance.

[0003] Existing integrated antenna solutions typically face the following technical bottlenecks:

[0004] 1. Inter-antenna coupling interference problem: When multiple antenna elements are densely arranged in a compact space, the electromagnetic coupling effect is significant, which leads to a decrease in signal isolation. Especially in orthogonal polarization scenarios, it is difficult to balance space occupation and isolation requirements.

[0005] 2. Limitations of grounding methods: Traditional antennas mostly use welding or fixed grounding structures, which leads to high assembly complexity, and the grounding reliability is easily affected by mechanical stress or environmental factors after long-term use.

[0006] 3. Output antenna design defects: Existing output antennas usually adopt a common ground or common routing design, which leads to increased signal crosstalk, affects the efficiency of multi-channel parallel transmission, and makes it difficult to meet the signal integrity requirements of high-frequency (such as millimeter wave) communication.

[0007] 4. Insufficient interface flexibility: Multi-band antenna components are often connected through a single interface or non-independent cable, which can easily cause signal transmission loss and inter-band interference, making it difficult to adapt to diverse communication protocol requirements.

[0008] To address these issues, existing technologies have attempted to improve isolation by adding shielding layers or optimizing antenna layout, but this often comes at the cost of device miniaturization. For example, existing technologies propose reducing coupling through layered wiring, but this does not solve the reliability problem of grounding multiple antennas; existing technologies use directional couplers to optimize output performance, but this increases system complexity.

[0009] The above background information is provided only to assist in understanding the utility model concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application, nor does it necessarily provide technical teaching. In the absence of clear evidence that the above information was disclosed before the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

Detailed Implementation

[0043] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0044] like Figure 1-5As shown, this utility model provides an integrated antenna, including: a housing and a multi-frequency integrated interface assembly 1, wherein multiple independent antenna units are integrated within the housing; the multi-frequency integrated interface assembly 1 includes a main antenna port, an auxiliary antenna port, and an output antenna port, which are connected to each antenna unit via discrete cables 5; each antenna unit includes: a main antenna 2, an auxiliary antenna 3, and at least two sets of output (MIMO) antennas 4, wherein the main antenna 2 and the auxiliary antenna 3 are orthogonally distributed and the spacing between them is greater than a preset threshold, and the output antennas 4 are independently configured with wiring between them; the main antenna 2 and / or the auxiliary antenna 3 are grounded through a pressure contact grounding mechanism, and the output antennas 4 may be grounded or ungrounded.

[0045] This invention proposes an integrated antenna and vehicle. Through an orthogonally distributed main and auxiliary antenna layout, an independently routed output antenna configuration, and a pressure contact grounding mechanism, it effectively solves key technical problems such as multi-antenna coupling, grounding reliability, and interface flexibility, meeting the requirements of wide bandwidth, high efficiency, and isolation of integrated antennas to adapt to the needs of future high-frequency and high-density communication scenarios.

[0046] Preferably, such as Figure 2-5 As shown, the outer casing includes: a first plastic outer casing 7, within which a radiating medium 6 is disposed; the pressure contact grounding mechanism includes: multiple pressure applying elements 11 and screws 18; the pressure applying elements 11 are disposed on the inner bottom wall of the first plastic outer casing 7, with their height difference forming a gradient pressure distribution; the screws 18 are disposed at both ends of the long axis of the first plastic outer casing 7; the screws 18 control the deformation of the radiating medium 6 by tightening torque to achieve grounding of the main antenna 2 or the auxiliary antenna 3; by setting pressure applying elements with height differences on the inner bottom wall of the first plastic outer casing 7, a gradient pressure distribution is formed. This design ensures that the contact pressure between the radiating medium 6 and the grounding point is not uniformly distributed, with higher pressure in key areas (such as the high-frequency grounding end). Larger diameter ensures better contact and reduces overall mechanical stress. The screws 18 at both ends of the long axis of the first plastic shell 7 precisely control the compression deformation of the radiator medium 6 by the tightening torque. Adjusting the deformation allows for fine-tuning of the inductance / capacitance parameters of the antenna grounding path, compensating for parasitic effects in the high-frequency band and improving antenna efficiency. Gradient pressure combined with the pre-tightening force of the screws 18 forms a self-locking structure, maintaining contact stability under vibration conditions. The orthogonal layout of the main antenna 2 and auxiliary antenna 3, combined with gradient pressure grounding, achieves dual decoupling of polarization isolation and grounding path separation. This pressure-contact grounding mechanism improves antenna performance and increases bandwidth efficiency within a limited space through gradient pressure distribution, deformation-controlled impedance matching, and polarization-coordinated grounding layout.

The radiating plate 10 at the other end of the radiator realizes the medium is engaged with the contact point 8. One side wall of the radiating plate 13 on one side of the radiator realizes the medium abuts against the side wall of the pressure applying member 11. The radiating plate 9 at one end of the radiator realizes the medium has multiple radiating plate grooves 12. The protrusion 14 of the pressure applying member is disposed in the radiating plate groove 12; the protrusion 14 of the pressure applying member is embedded in the radiating plate. The groove 12 forms a physical snap-fit, providing longitudinal positioning constraints to ensure that the radiator medium 6 does not slip axially during vibration or thermal deformation. The depth of the groove 12 and the height of the protrusion 14 are matched to ensure that the contact pressure is evenly distributed along the edge of the groove 12, avoiding metal fatigue fracture caused by stress concentration at a single point. The array of grooves 12 combined with the height difference layout of the pressure-applying components 11 forms a segmented pressure gradient. High pressure is applied to the protrusion 14 in the central region to enhance the contact reliability of the high-frequency grounding path. The pressure gradient decreases in the edge region to buffer the shear stress of the radiator sheet caused by the deformation of the outer shell.

The isolation blocks 15 are disposed between the radiating sheet 13 on the side of the radiating medium and one side wall of the first plastic shell 7.

[0050] Preferably, such as Figure 2-3As shown, the output antenna 4 also includes: two independent antenna traces; a grounding configuration structure, wherein the grounding configuration is achieved through conductive vias 20 on the radiating medium 6; the two antenna traces adopt an orthogonal layout (vertical and horizontal polarization are separated), and mutual coupling interference is reduced through spatial orthogonality; the conductive via array 20 is distributed along the edge of the radiating medium to form a surrounding grounding shielding layer, thereby improving the uniformity of surface current distribution and achieving high-efficiency radiation, low-interference transmission and stability in harsh environments for multi-band antennas in a miniaturized space.

[0051] Preferably, such as Figure 2-3 As shown, the outer shell includes: a third plastic shell 21, wherein a heat sink 22 and a WIFI antenna board 23 are provided inside the third plastic shell 21; high heat flux density heat dissipation and high gain wireless transmission are simultaneously achieved in the miniaturized integrated antenna.
