Problems solved by technology
[0003] In the development of portable wireless communication devices, on the one hand, more and more compatible communication solutions are required. On the other hand, it must also have advanced electrical performance of the antenna, which can transmit and receive RF (Radio Frequency, RF radio frequency) more effectively. Signal energy; because the current technology is still unable to fully integrate the entire multi-band antenna into the chip of the semiconductor process, in portable wireless communication devices, in addition to the core system chip, the multi-band antenna is another component that directly affects the communication transmission performance. The key components; and users or consumers are more interested in smaller built-in antenna wireless communication devices, but the built-in multi-band antenna is difficult to avoid communication signal degradation due to handheld use
[0004] Therefore, the existing technology still needs to be improved and developed

The invention discloses an enclosed type multiband aerial and a wireless communication device thereof. The multiband aerial comprises a transmitting body, a feed-in terminal and an earth terminal which are connected to the transmitting body, wherein a multiband tuning unit is arranged on the transmitting body, and the feed-in terminal and the earth terminal are respectively used for electrically connecting with respective access point in the wireless communication device on a printed circuit board, wherein the transmitting body forms an annular enclosed type structure; and the feed-in terminal and the earth terminal are connected to the outer side of the enclosed type structure. Because the transmitting body of the multiband aerial adopts the annular enclosed type structure, a resonance current produced by the multiband tuning unit on the transmitting body in each resonant mode forms a self loop in the annular enclosed type structure, the amplitude of a radio-frequency current on the printed circuit board is reduced, the interference of the multiband aerial on a user in contact with the wireless communication device is weakened, and thus, the phenomenon of communication signal degradation when the user holds the wireless communication device by hands is avoided.
Description
technical field [0001] The invention relates to the field of multi-band antennas of wireless communication devices, and more specifically, the improvement relates to a closed multi-band antenna and a wireless communication device thereof. Background technique [0002] With the rapid development of wireless communication technology, portable wireless communication devices such as mobile phones and PDAs (personal digital assistants, personal digital assistants) have also been rapidly promoted and popularized, and have become an indispensable part of modern daily life. [0003] In the development of portable wireless communication devices, on the one hand, more and more compatible communication solutions are required. On the other hand, it must also have advanced electrical performance of the antenna, which can transmit and receive RF (Radio Frequency, RF radio frequency) more effectively.
