Description
Technical field
The utility model is related to a kind of combined antenna monitored with parking stall with communication function.
Background technology
With increasing sharply for automobile quantity, parking management becomes more and more important.At present, either stop in parking lot
Car, still indoors, outdoor or curb parking, still artificial mode is managed in most cases.One side custodian
Member's labor intensity is very big, the possibility for parking fee loss on the other hand also easily occur., can not be real-time for driver
Solve the situation on parking stall.
Although also have taken using loop coil, video, ultrasonic wave or microwave come unloading lot detection or the free time state,
It is the problem of all having such or such.As easily influenceed by weather, the problems such as detection range is too near.
Utility model content
The purpose of this utility model seek to provide it is a kind of detect vehicle using microwave frequency band double antenna mode, and with non-
Sight (NLOS) radio frequency band transmits the compound day with parking stall monitoring and communication function of information of vehicles as communications band
Line.
The utility model is adopted the following technical scheme that：
It is a kind of monitored with parking stall and communication function combined antenna, including PCB and be arranged on PCB
On the first microwave antenna, the second microwave antenna and radio-frequency antenna.
It is preferred that, radio-frequency antenna is the helical antenna that frequency is 500MHz；
It is preferred that, the PCB is two-sided polytetrafluoroethylene (PTFE) (FR4) plate that thickness is 1 millimeter；
It is preferred that, first microwave antenna and the second microwave antenna are all 8GHz back of the body feedback rectangular microstrip antennas, wherein one
Individual 8GHz microwave antennas launch electromagnetic wave, and another 8GHz microwave antenna receives the electromagnetic wave of reflection；
Further, the dielectric substrate of first microwave antenna and the second microwave antenna is that dielectric constant is 2.2, thickness
For 1.6 millimeters of low-loss high-frequency medium plate, the size of low-loss high-frequency medium plate is 15 millimeters x15 millimeters, and antenna polarization is
Linear polarization；
Further, first microwave antenna and the second microwave antenna are arranged in the two ends of the PCB printed circuit board (PCB)s,
Distance is 60 millimeters, to improve the isolation of two microwave antennas.
The beneficial effect of the design is that the accuracy of detection to parking stall is high, and rate of false alarm is low, can reach that vehicle is accurately detected
Smoothly required with information transfer；And the isolation between micro-strip dual-mode antenna is high, mutual interference is small.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model；
In figure, 1 is PCB, and 2 be radio-frequency antenna, and 3 be the first microwave antenna, and 4 be the second microwave antenna.
Embodiment：
The utility model is described further with reference to the accompanying drawings and detailed description：
In Fig. 1,1 is PCB, and 2,3,4 are provided in radio-frequency antenna, the first microwave day in PCB 1 respectively
Line and the second microwave antenna；
It is preferred that, PCB 1 is two-sided polytetrafluoroethylene (PTFE) (FR4) plate that thickness is 1 millimeter；
It is preferred that, radio-frequency antenna 2 is the helical antenna that frequency is 500MHz；
It is preferred that, the first microwave antenna 3 and the second microwave antenna 4 are all 8GHz back of the body feedback rectangular microstrip antennas, one of them
8GHz microwave antennas launch electromagnetic wave, and another 8GHz microwave antenna receives the electromagnetic wave of reflection；
Further, the dielectric substrate of the first microwave antenna 3 and the second microwave antenna 4 is that dielectric constant is 2.2, and thickness is
1.6 millimeters of low-loss high-frequency medium plate, the size of low-loss high-frequency medium plate is 15 millimeters x15 millimeters, and antenna polarization is line
Polarization；
Further, the microwave antenna 4 of the first microwave antenna 3 and second is arranged in the two of the PCB printed circuit board (PCB)s 1
End, distance is 60 millimeters, to improve the isolation of two microwave antennas.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
