Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, do not limit the utility model.
As shown in Figure 1, 2, the utility model embodiment relates to a kind of antenna mutual interference spacer assembly, comprising:
Be provided with the isolation part 6 of empty regions, and,
Be arranged on the coupling part 5 of empty regions, wherein coupling part 5 comprises left side golden finger and right side golden finger, left side golden finger extend from left to right from isolation part and and leave gap between the isolation part on right side; Right side golden finger extend from right to left from isolation part and and leave gap between the isolation part in left side; Left side golden finger and right side golden finger interval in empty regions is arranged.
Wherein, isolation part 6, coupling part 5 (left side golden finger and right side golden finger) are made by conducting medium; Conducting medium can be the materials such as conducting foam, conductive fabric, Copper Foil or aluminium foil.
The empty regions of isolation part 6 refers to and cut out a part on isolation part 6, form one piece of white space (this region does not have isolation part), this region is non-close region, and namely empty regions has the regional connectivity outside an opening and isolation part 6 at least, makes empty regions be non-close region.
The shape of antenna mutual interference spacer assembly can adjust according to the needs of the layout of wireless network card or terminal, and such as, can be square, also can be circular, or even irregular figure; Empty regions also can be square, circular, or even irregular figure.
As shown in Figure 3,4, the present embodiment relates to a LTE (Long Term Evolution, Long Term Evolution) wireless network card product, comprises main and auxiliary two antennas, and layout type adopts normal arrangement.LTE wireless network card be required to meet LTE band1,2,4,5,8,17, the data transmission service of 28.
As shown in Figure 3, auxiliary antenna is placed on the place of wireless terminal near USB (Universal Serial Bus, USB) port one, and below USB port 1, arrange auxiliary antenna headroom position 2; Auxiliary antenna feed point 4 is positioned at the side of auxiliary antenna headroom position 2.Main antenna is placed on network interface card top, and arranges main antenna headroom position 3; Main antenna distributing point 7 is arranged on the top of main antenna headroom position 3.Two antennas all adopt conventional support to add FPC (Flexible Printed Circuit board, flexible print wiring board) form.The antenna arrangement of whole product has been optimal layout scheme, but in debug process, find between main spoke antenna disturb mutually very serious.In actual test, low-frequency range TRP (total radiated powe, the total radiant power) index of main antenna is as follows:
band5：17.3dB，band8：16.2dB，band28：15.7dB。
Auxiliary antenna receiving sensitivity TIS (Total Isotropic Sensitivity, omnidirectional sensibility) index is as follows:
band5：-86.7dB，band8：-87.8dB，band28：-85.9dB。
