I communication products to achieve multi-input and multi-output functions, first to divide the space into many channels, _ provide multiple antennas 3 M426890 field type. Due to the use of multiple sets of antennas, the problem of mutual interference between antennas has become one of the key considerations in design. Therefore, how to effectively improve the antenna isolation of wireless communication products has become an issue that the industry is striving for. [New content] Therefore, the main purpose of this creation is to provide a wireless communication device to improve antenna isolation. The present invention discloses a wireless communication device including a circuit board; a first antenna formed on the circuit board and having a first feed end formed in a first position; and a second antenna formed on the second antenna The circuit board has a second feed end formed in a second position, wherein the circuit board has a substantially rectangular shape, and the first position and the second position are substantially located at a long edge of the circuit board. And a certain distance apart. [Embodiment] Please refer to Fig. 1, which is a schematic view of a wireless communication device 10 according to a first embodiment of the present invention. The wireless communication device 10 supports a multi-input multi-output (MIMO) communication technology, which includes a circuit board 1 , a first antenna 102 , and a first antenna 1 〇 4 ^ circuit board 1 A circuit for setting a wireless communication function, such as a radio frequency circuit, is generally rectangular, and has a length generally between 100 mm and 130 mm, and a width generally between 5 mm and 70 mm. The first antenna 102 and the second antenna 1〇4 can be used for various antennas whose operating frequency band is between 6 〇〇mHz and 3 GHz, and are formed on the circuit board 1 around the edge of the circuit board 100. On the M426890. In addition, the first antenna 102 and the second antenna 104 respectively transmit and receive RF signals through a first feed end 106 and a second feed end 108, and the first feed end 106 and the second feed end 108 are formed. The position is located substantially at the edge of one of the long sides of the board 1 and at a distance D. Wherein, the distance D is preferably less than 40 mm, and the distance between the first feeding end 1〇6 and the second feeding end 108 to the shortest side of the closest is greater than 30 mm; in this case, the isolation can be effectively improved. The first antenna 102 and the second antenna 104 are prevented from interfering with each other, thereby improving antenna efficiency. For example, please refer to FIG. 2. FIG. 2 is a schematic diagram showing the antenna efficiency when the first antenna 102 and the second antenna 1〇4 are disposed in the wireless communication device 10 and only the first antenna 丨〇2 is disposed. As shown in FIG. 2, when the wireless communication device 1 is configured to simultaneously configure the first antenna 1〇2 and the second antenna 104, the difference in antenna efficiency when the first antenna 1〇2 is disposed is not large.

It should be noted that the wireless communication device 1 shown in Fig. 1 is an embodiment of the present invention, and components such as a casing and a port (such as a USB connector) are omitted for the sake of brevity. However, those skilled in the art can make various modifications as they are, and are not limited thereto. For example, the first antenna 1〇2 and the second antenna 1〇4 need only ensure that the first feeding end 1〇6 and the second feeding end 108 are separated by a distance D of less than 4〇mm, and the first antenna The first and second antennas 104 extend from the long side to the short side along the periphery of the circuit board 100. In addition, as is known in the art, the __ rate is related to the ship's diameter. Therefore, the first antenna and the 5th M426890 two antennas 104 should be properly adjusted according to the required operating frequency band. + The needs of the same system.
