Hereinafter will describe the utility model with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
According to embodiment of the present utility model, provide a kind of terminal.
Comprise according to terminal of the present utility model: the MIMO antenna, wherein, this MIMO antenna is arranged on the PCB of this terminal.
In preferred implementation process, the MIMO antenna directly can be printed on the PCB.
With the antenna of terminal be arranged in this terminal printed circuit board (PCB) (for example, be directly printed onto on the circuit board), having solved in the correlation technique antenna adopts steel disc or FPC attached on the support, need be to support and antenna die sinking tool, cause the very high problem of cost, and then can save cost, improve the radiation efficiency of antenna.
Wherein, above-mentioned terminal not only can be data card Terminal Type (for example, USB Modem), can also be mobile terminal device (for example, mobile phone) etc.
The antenna arrangement of USB Modem is described below in conjunction with Fig. 1.
Fig. 1 is the antenna arrangement figure according to the USB Modem of the utility model preferred embodiment.As shown in Figure 1, the antenna of this USB Modem comprises: main antenna 1 and diversity antenna 2; Wherein, main antenna is positioned at the headroom district of the PCB end of USB Modem; Diversity antenna is positioned at the headroom district of the PCB side of USB Modem.
In specific implementation process, be to realize the function that USB Modem (modem) diversity transmits and receives, what require that the efficient of major-minor antenna will try one's best is approaching, and for example, the antenna efficiency value differs usually and is no more than 10%.
Preferably, as shown in Figure 2, above-mentioned main antenna 1 is the grading structure that broadens step by step along radio frequency testing seat 3.Being divided into two-stage from the A point to D point width widens step by step.From the D point, the main antenna radiant body is tapered to be widened gradually, and electric current comparatively is evenly distributed on the radiant body.Main antenna has formed the structure that is similar to monocone antenna, and desirable monocone antenna has the ultra broadband characteristic, and this utility model main antenna has been inherited this characteristics, has realized broadband character.
In preferred implementation process, narrow structure (AB section) live width of above-mentioned main antenna 1 can be set to 0.31 millimeter usually.
Preferably, because the restriction of overall dimension, auxilliary antenna headroom district is narrow and small, and main antenna and/or diversity antenna can adopt elongated monopole antenna cabling form.
