Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that term " front ", "upper", "lower", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal" is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description originally
Invention and simplified description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific side
Position construction and operation, therefore be not considered as limiting the invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be to be connected directly, the connection inside two elements can also be can be indirectly connected through an intermediary.For this field
For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
As depicted in figs. 1 and 2, a kind of anti-string for electronic tag reads transmitting antenna, including shell 100, pcb board 200
With metal wiring terminal 300, pcb board 200 is encapsulated in shell 100, and the outside of shell 100 is arranged in metal wiring terminal 300, and
Metal wiring terminal 300 is connected with pcb board 200, which is connected with reader, is used for and reader
Communication.Shell 100 is integrally formed, and the integral waterproofing grade of such transmitting antenna can achieve IP68 grades.It is arranged on pcb board 200
There is the antenna stack 400 of strip, antenna stack 400 is copper foil antenna, after metal wiring terminal 300 is connected with reader, for hair
It penetrates antenna and provides energy, antenna stack 400 launches the electromagnetic wave of specific frequency.Strip antenna stack 400 makes field homogeneity point
Cloth, size tab can be read in antenna magnetic field radiation scope.
The length of antenna stack 400 is 78.6mm, and the width in middle position is 6mm, and is arranged in both ends wedge angle, antenna stack
400 angle of radiation is straight up each 30 degree toward two sides, and the radiation length of antenna stack 400 is 1-15cm.The present embodiment provides
Transmitting antenna be mainly used in biologic medical field, most common operating distance is 3cm, so in range transmission antenna 3cm
The radiating surface of high position is that length is slightly longer and 78.6mm, the major width in middle position are about 9.46mm.Such radiating surface
Width is small, and the angle of radiation of electromagnetic wave is small, and adjacent electronic tag will not be made to receive the electromagnetic wave, avoids that string reading occurs.
Pcb board 200 is provided with the opposite one side of antenna stack 400 and is provided with metal plate 500, which can be with
Completely cut off electromagnetic wave, the magnetic board for preventing antenna stack 400 from being radiated is projected from the face.The wave frequency that this transmitting antenna is radiated
For the frequency electromagnetic waves of 850MHZ-950MHZ, the setting of metal plate 500 is also used to adjust for the impedance of pcb board 200, be allowed to
The wave frequency of the high band matches, enhanced rad intensity, improves the transmitting and receptivity of transmitting antenna.
