Description
Technical field
The present invention relates to car antenna technology, specifically automobile Bluetooth receiving and transmitting signal device.
Background technology
Automobile Bluetooth receiving and transmitting signal device is indispensable assembly in Hyundai Motor, and it is widely used in the multiple fields such as mobile communication.Bluetooth antenna becomes one of key issue that must solve.Require that antenna will be accomplished minimum as far as possible, powerful Received signal strength ability will be had simultaneously, avoid occurring with during mobile phone line the situation of going offline.So, there is low section, the antenna of the outstanding properties advantage such as easy of integration is used widely on automobile.In plane single pole sub antenna, there is a kind of inverted L-shaped plane single pole sub antenna, in the world to this has been research, on theoretical analog simulation, IEEE802.11a/b/g standard-required can be met simultaneously, its design form is simpler, and in the requirement meeting bandwidth, volume also can further reduce.
Summary of the invention
The object of the present invention is to provide a kind of automobile Bluetooth receiving and transmitting signal device, have devised a kind of miniaturized floor and feeder line coplanar antennae, while reducing antenna size, improve the performance of antenna.
Object of the present invention is achieved through the following technical solutions: automobile Bluetooth receiving and transmitting signal device, comprise medium substrate, medium substrate is sticked the first lateral radiation paster of strip and the left side radiation patch of strip, the right side radiation patch of strip, second lateral radiation paster of strip, medium substrate has also been sticked 2 metal floors, medium substrate has also been sticked feed main line, metal floor lays respectively at the both sides of feed main line, one end of feed main line is connected with in the middle part of the first lateral radiation paster, first lateral radiation paster and feed main line form T-shaped structure, left side radiation patch is connected with the left end of the first lateral radiation paster, right side radiation patch is connected with the right-hand member of the first lateral radiation paster, one end of second lateral radiation paster is connected with left side radiation patch one end away from the first lateral radiation paster, the left and right of the first lateral radiation paster is to the left and right of axis and the second lateral radiation paster to axis being parallel.
Based on said structure, the present invention, by the basis of the original microstrip-fed plane single pole sub antenna of falling L, changes the form of its feed, develops a kind of plane single pole sub antenna of falling L-U of coplanar wave guide feedback.Emulation and actual measurement show that this antenna all has good impedance matching and radiation characteristic in three frequency band ranges of WLAN.
The reason selecting plane single pole sub antenna is that, relative to microstrip antenna, its band is roomy, and volume is little and easily conformal.Plane single pole sub antenna is different from the structure of microstrip antenna to be: be removed at the metal floor of dielectric substrate opposite side corresponding to metal radiation paster, namely have employed partly plate structure.The bandwidth of microstrip antenna is low, because its Q value is large, namely between radiant panel and floor, stores a large amount of energy.The corresponding floor of the radiant panel of plane single pole sub antenna eliminates, and increases radiation resistance, and the energy radiate also increases greatly, and Q value diminishes, and bandwidth increases.Select the form of coplanar wave guide feedback, by floor and radiant panel coplanar, bandwidth is in turn increased, and more compact structure.But owing to lacking effective isolation between antenna and co-planar waveguide, cause antenna performance to be subject to the impact of co-planer waveguide dimension more serious.
The present invention passes through the folding in meander technology, by the planar monopole of the coplanar wave guide feedback shape of falling L-U antenna.Size after folding is than originally there being larger reduction.The length of antenna current transmission direction can be estimated by formula, antenna designed by the present invention need meet the requirement of covering two frequency ranges, in order to make compact overall structure, miniaturization, broadband, script axis is in left side radiation patch on same straight line by the present invention and the second lateral radiation paster bends, second lateral radiation paster and left side radiation patch are carried out vertically be arranged to L shape structure, it can reduce the volume of whole antenna, and its performance parameters is unaffected simultaneously.
The relative dielectric constant of medium substrate is 4.4, thickness is 1.6mm.
Gap between feed main line and metal floor is 0.6mm.
The invention has the advantages that: the second lateral radiation paster and left side radiation patch are carried out vertically being arranged to L shape structure, it can reduce the volume of whole antenna, its performance parameters is unaffected simultaneously.
