[0022] The following is a detailed description of the high-performance terminal antenna proposed in this utility model, combined with the accompanying drawings and specific embodiments. It should be noted that the drawings are highly simplified and not precisely scaled, and are intended solely to facilitate and clearly illustrate the embodiments of this utility model. Furthermore, the structures shown in the drawings are often partial to the actual structures. In particular, different drawings may require different emphases and may use different scales.
[0023] With the advancement of science and technology and the rapid development of wireless communications, electronic products such as smartphones, tablets, and laptops are constantly being updated and replaced. Users are also placing higher and higher demands on products, requiring them to be intelligent and metallized. Most products are made of all-metal materials, which also requires antennas to be more miniaturized and support wider frequency bands. Currently, most laptops use all-metal shells and narrow-frame designs, which makes antenna debugging considerably more difficult. The small antenna space and poor environment result in substandard antenna performance. In view of this, the present invention is indeed necessary to propose a new type of high-performance terminal antenna and a mobile terminal using the high-performance terminal antenna to solve the above problems.
[0024] The high-performance terminal antenna of the present invention can be applied to mobile terminals such as laptop computers, tablet computers, or larger mobile phones. The high-performance terminal antenna will be described below using a laptop computer as an example.
[0025] like Figure 1As shown, the present invention provides a high-performance terminal antenna, which is disposed on a metal surface of a laptop computer. Specifically, the high-performance slot antenna assembly includes a first radiating unit 10 and a second radiating unit 20.

The slot assembly includes a first slot 21 and a second slot 22. The first radiating branch 11 and the second radiating branch are both disposed on the substrate, which is disposed on and covers the first slot 21 and the second slot 22.
[0026] With this configuration, the high-performance terminal antenna of the present invention not only enables the mobile terminal to broaden the overall antenna radiation frequency band in an all-metal environment, but also effectively improves and enhances the overall antenna radiation efficiency.

The part of the first radiating branch that does not cover the first slot is preferably configured as a 2.4GHz frequency band parasitic, so that coupling with the first slot will produce 2.4G resonance.
[0031] Preferably, the length of the first gap 21 is 40 mm and the width is 2.5 mm; the length of the second gap 22 is 19 mm and the width is 2.5 mm. The first gap 21 and the second gap 22 are coupled to form a coupling gap, and the spacing between the coupling gaps is 1.5 mm.
[0032] In the present invention, the first radiation unit is preferably a PCB antenna, which is arranged relative to the second radiation unit and the first gap and the second gap. It should be noted that there should be no LCD or other metal blocking on the first radiation unit to prevent affecting the antenna performance.
[0033] like Figure 2 The S11 simulation diagram of a single slot antenna is shown as follows: Figure 3 The figure shows the S11 simulation diagram of the double-slot antenna, which is significantly better than the S11 of the single-slot antenna in the 2.4G and 5G frequency bands, and the antenna efficiency is also significantly improved.
