Description

Technical Field

[0001] The utility model belongs to the technical field of antennas, and in particular relates to an intelligent terminal communication antenna component and an intelligent terminal. Background Art

[0002] With the advancement of wireless communication technology, the variety of IoT antennas has increased significantly. Most IoT antennas are in the form of rubber sticks and are typically placed outside IoT devices, securely connected to them via cables and adapters. IoT antennas primarily operate at the 433MHz frequency, and the efficiency of 433MHz antennas directly impacts actual user experience. For full-screen smart devices, lightweight and thin designs are becoming the mainstream, with requirements for smaller antenna sizes, some even requiring integration into IoT devices. However, the thinner overall design of full-screen smart devices reduces the clearance area for antennas, making the structural environment more complex and significantly impacting antenna design, efficiency, and bandwidth.

[0006] In the smart terminal communication antenna assembly of the present invention, the feeding point, the radiator and the grounding point form the antenna structure of the IFA routing, the radiator generates resonance, the control resonance area is clear, and the adjustment and optimization are convenient and quick; an antenna clearance area is left between the radiator and the antenna substrate, which is beneficial to improving the antenna efficiency; at the same time, the smart terminal communication antenna assembly can be used for routing on the smart terminal motherboard, and can be built into the interior of the smart terminal through the circuit substrate without occupying external space. The smart terminal communication antenna assembly occupies a small space, is suitable for light and thin devices, and reduces costs.

[0007] Furthermore, the circumference of the radiator is one quarter of its resonant wavelength. The length of the radiator is controlled to achieve optimal antenna efficiency.

[0009] Furthermore, the radiator is in the shape of an elongated strip, which is convenient for adjusting the length and has a uniform electric field, so as to facilitate controlling the resonant frequency of the radiator.

[0010] Furthermore, the grounding point is located at an edge of the circuit substrate, and the radiating segment of the radiator extends away from the grounding point and is parallel to the length or width of the circuit substrate. The radiator is parallel to the length or width of the circuit substrate to ensure that it is as close to the edge of the smart terminal motherboard as possible and away from other circuit modules on the smart terminal motherboard to avoid interference and improve antenna efficiency.
