The invention discloses a PCB used for connecting antennas. The PCB, which is of a multilayer board structure, comprises an upper outer board, a lower outer board, and multiple inner boards between the upper outer board and the lower outer board. The upper outer board is provided with an antenna feed point line, the lower outer board is provided with an extended ground in a position right corresponding to the antenna feed point line, and the position, right corresponding to the antenna feed point line, on each of the multiple inner boards is hollowed out to form a clearance area, wherein the antenna feed point line is used for connecting antennas, and the extended ground is electrically connected with the ground line of the PCB. The invention further discloses an antenna assembly adopting the PCB, and a mobile terminal comprising the antenna assembly. According to the PCB provided by the invention, the performance of antennas is improved through coupling between the antenna feed point line on the upper outer board of the PCB and the extended ground on the lower outer board of the PCB. The PCB is simple and convenient to make, and has the advantage of being capable of reducing the cost of antenna development.
Description
technical field [0001] The present invention relates to the field of antenna design, in particular to a PCB board used for connecting antennas, and also to an antenna assembly using the aforementioned PCB board and a mobile terminal including the antenna assembly. Background technique [0002] Total isotropic sensitivity TIS (Total Isotropic Sensitivity) is one of the important parameters to evaluate the receiving performance of the antenna. It reflects the situation of the receiving sensitivity index of the mobile phone on the entire radiation sphere, reflects the receiving sensitivity of the whole mobile phone, and the conduction of the mobile phone. Sensitivity is related to the radiation performance of the antenna. [0003] At present, the size of smart mobile terminals such as mobile phones and tablet PCs is becoming thinner and lighter, and the market has higher and higher requirements for the appearance of smart mobile terminals. At the same time, operators have incre...
