The direction array of circle is made up of multiple directional aerials to unit, and microwave-medium is additionally provided with the direction finding unit.
It is described fixed in a kind of preferred embodiment of the closely bluetooth position read head range unit that the utility model is provided
PCB microstrip antennas are used to antenna.
It is described micro- in a kind of preferred embodiment of the closely bluetooth position read head range unit that the utility model is provided
Ripple medium use dielectric constant for 90 microwave dielectric ceramic.
Compared with prior art, the beneficial effect of the closely bluetooth position read head range unit that the utility model is provided
It is：
First, the utility model utilizes direction-finding station principle, measures Bluetooth signal direction and is measured by two test points
Both direction angle, then the distance of signal source distance measurement point is calculated by trigonometric function principle, measurement is accurate, using effect
It is good；
2nd, the circular direction array that the direction finding unit for using is made up of multiple directional aerials, can accurately catch
Signal source is caught, azimuth-range can accurately be calculated by the signal processing unit, improve the accuracy rate of device；
3rd, the direction finding unit is using PCB microstrip antennas and adds the dielectric constant microwave-medium higher, reduces
The speed of electromagnetic wave, shortens the wavelength of electromagnetic wave, thus can greatly reduce the size of the directional aerial, not only just
In installation, production cost is also reduced.
