Abstract
Disclosed is an antenna structure suitable for being shared by wireless communication modules, comprising a plurality of wireless communication modules (4 -1, 4 - 2, , 4 - N) and a set of match circuit units (3 - 1, 3 - 2, , 3 - N) corresponding to the wireless communication modules. The utility model is characterized in that the antenna structure also comprises a shared antenna (1) and a switching circuit unit (2) connected with the shared antenna (1); wherein the switching circuit unit (2) selects one match circuit unit (3 - i) of the match circuit units (3 - 1, 3 - 2, , 3 - N) to connect with, thus the shared antenna (1) is communicated with the wireless communication module (4 - i), i is any of the natural number 1, 2, , N. The antenna structure of the utility model has the advantages that the antenna number is obviously reduced and the antenna occupying space is obviously saved.
Description
Technical field
The utility model relates to a kind of antenna structure, refers in particular to the structure of the shared antenna of a plurality of wireless communication modules in a kind of portable set.
Background technology
The all integrated wireless communication module of different operating frequency in the increasing portable set, for example bluetooth module and WiMAX module, wireless communication module transmits and receives signal via antenna.At present, common way is to be the different different antennas (as shown in Figure 1) of wireless communication module design, and is placed in the inside or the outside of portable set.But these antenna will take very large space, like this, the miniaturization of portable set has been brought very big obstacle.
Summary of the invention
In sum, how to solve existing wireless communication module and cause taking very large space owing to being equipped with antenna separately, hinder the miniaturization of portable set, it is technical problem to be solved in the utility model, for this reason, the purpose of this utility model is, a kind of suitable wireless communication module antenna shared structure is provided, make a plurality of wireless communication modules share an antenna, reduce antenna occupation space in the portable set.
For achieving the above object, the utility model adopts following technical proposals: each wireless communication module match circuit unit of all connecting is connected with shared antenna by the switch switching circuit unit then.The working frequency range of sharing antenna has covered the working frequency range of wireless communication module.Described switch switching circuit unit can be implemented between the different wireless communication modules and switches.The performance of antenna changes along with the difference of match circuit unit.
Described match circuit unit can be a lc circuit.Lower in operating frequency, the parasitic parameter of circuit is not clearly the time, can adopt lc circuit as the match circuit unit.
Described match circuit unit can be the microstrip line circuit.When operating frequency than higher, when the parasitic parameter of circuit is apparent in view, then adopt microstrip line as the match circuit unit.
Described wireless communication module operating frequency is different.
One of described wireless communication module is a bluetooth module.
One of described wireless communication module is the WiMAX module.
The utility model has the advantages that: same antenna shared in the selection that can make different wireless communication modules pass through the match circuit unit, reached to reduce number of antennas, saves the purpose that antenna takes up room.
Description of drawings
Fig. 1 is existing a plurality of many antennas of wireless communication module schematic diagram;
Fig. 2 is the schematic diagram that a plurality of wireless communication modules of the present invention are shared antenna.
Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Shown in Figure 2 is the structure that a plurality of wireless communication modules are shared antenna.Comprise and share antenna 1, be used to switch the switch switching circuit unit 2 of different match circuits unit, and be used for the different radio communication module the match circuit unit (3-1,3-2 ..., 3-N) and the wireless communication module unit (4-1,4-2 ..., 4-N).When needing in the portable set to use wireless communication module 4-1, switch switching circuit unit 2 switches to match circuit unit 3-1, the 3-1 conducting of match circuit unit, and wireless communication module 4-1 can be by sharing antenna 1 reception and transmitting; When needing in the portable set to use wireless communication module 4-2, switch switching circuit unit 2 switches to match circuit unit 3-2, the 3-2 conducting of match circuit unit, and wireless communication module 4-2 can be by sharing antenna 1 reception and transmitting.
From present embodiment, can reason out in the present invention, it has a shared antenna 1, a plurality of wireless communication modules (4-1,4-2, match circuit unit 4-N) and correspondingly (3-1,3-2 ... 3-N), when switch switching circuit unit 2 switches to match circuit unit 3-i (i is arbitrary number among the natural number 1-N), the 3-i conducting of match circuit unit, wireless communication module 4-i can be by sharing antenna 1 reception and transmitting.
Claims (6)
