Of course, the electric shock terminal 2 is a branch structure extending from the frame body 1, and the length, the distance and the like of the branch structure can be designed according to different product requirements.
In the present embodiment, the contact terminals 2 are extended from the first body portion 11 and the second body portion 12, respectively.
For example, when the contact terminal 2 is used as an antenna structure in combination with other electronic components (not shown), the contact terminal 2 may be used as a feed terminal and a ground terminal. The contact terminal 2 and the first body 11 form a first antenna unit 200, and the contact terminal 2 and the second body 12 form a second antenna unit 300. The first antenna unit 200 and the second antenna unit 300 may be designed and adjusted in their form structures according to actual needs to implement communication in different frequency bands. Thereby realizing the support of the multifunctional frame 10 and the multifunction of acting as an antenna.
Please refer to fig. 2, which is a schematic exploded view of a communication device according to the present invention. The present invention further provides a communication device 100, which comprises an upper cover 20, a lower cover 30 covering the upper cover 20 and enclosing a receiving cavity (not numbered) together with the upper cover, a circuit board 40 fixed in the receiving cavity, and the multifunctional frame 10 provided by the present invention. The communication device 100 of the present invention mainly refers to portable mobile communication devices, such as mobile phones and IPADs.

The structure of the multifunctional frame 10 is designed according to the space and gap between the electronic components inside the communication device 100, such as the circuit board 40 and other components (not shown), so that the gap space inside the communication device 100 is effectively utilized, no extra space is occupied, and the overall volume of the communication device 100 is reduced.
Specifically, the multifunctional frame 10 further comprises a plurality of limiting and supporting parts 3 respectively fixed on two sides of the frame body 1, wherein the limiting and supporting parts 3 are respectively abutted against the upper cover 20 and the lower cover 30 and used for limiting the upper cover 20 and the lower cover 30, so that the supporting stability is better and the assembling efficiency is higher. Preferably, the position-limiting support part 3 is made of the amorphous metal material and is integrally formed with the frame body 1, so as to provide buffering support protection for the upper cover 20 and the lower cover 30, and prevent the upper cover 20 or the lower cover 30 from being broken due to excessive instantaneous pressure (such as falling impact). The reliability of the communication device is increased.

The frequency bands of the first antenna unit 200 and the second antenna unit 300 can be realized by designing the structural shapes of the first body portion 11 and the second body portion 12 according to needs. For example, in the present embodiment, the first antenna unit 200 includes a top-graded antenna 201 and a triple-entry antenna 202; it is possible that the second antenna unit 300 comprises a bottom main antenna 301.
Fig. 3 is a graph showing the comparison of the antenna efficiency (low frequency band) of the multifunctional frame of the present invention as an antenna with that of a conventional metal antenna. The antenna efficiency curve graph shows the radiation performance of the antenna, the performance is better the closer the Y value is to 0, and the X axis shows the frequency.
The multifunctional frame 10 was tested for efficiency as an antenna with a general metal antenna (here, an aluminum antenna) at a low frequency band, respectively, and the results are as follows:
| frequency (MHz) | Aluminum antenna efficiency | Efficiency of amorphous metal antenna |
| 780 | -7.80059 | -6.09614 |
| 800 | -6.90199 | -5.77714 |
| 820 | -5.45155 | -4.87802 |
| 840 | -5.36831 | -5.07165 |
| 860 | -5.92259 | -5.49287 |
| 880 | -6.82634 | -5.90938 |
| 900 | -8.31208 | -6.75303 |
| 920 | -9.44075 | -7.32898 |
| 940 | -9.7111 | -7.59948 |
| 960 | -9.32768 | -7.94655 |
Fig. 4 is a graph comparing the antenna radiation performance of the multifunctional frame of the present invention as an antenna with that of a conventional metal antenna. The antenna radiation performance curve represents an S11 parameter of an antenna feed end, namely how much energy flows into the antenna for radiation, and the smaller the Y value is, the less energy overflow is represented, namely the more energy flows into an antenna port, and the X axis is frequency.
From the test curves shown in fig. 3 and fig. 4 and the above data, it can be seen that the low-frequency center frequencies of the main antenna S11 curves of the two materials are identical, and the efficiency peaks are very close, so that the material characteristics have little influence on the low-frequency band of the antenna, and the error is within 0.5 dB.
From the test results, the amorphous metal material and the aluminum material antenna have antenna radiation characteristics which are very close to each other, and can be used as an antenna structure.
