Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "front", "upper", "lower", "left", "right", "vertical", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, a cross-reading prevention transmitting antenna for an electronic tag includes a housing 100, a PCB 200 and a metal terminal 300, the PCB 200 is enclosed in the housing 100, the metal terminal 300 is disposed outside the housing 100, and the metal terminal 300 is connected to the PCB 200, the metal terminal 300 is connected to a reader for communicating with the reader. The housing 100 is integrally formed so that the overall waterproof rating of the transmitting antenna can reach IP 68. The PCB 200 is provided with a strip-shaped antenna layer 400, the antenna layer 400 is a copper foil antenna, the metal wiring terminal 300 provides energy for transmitting the antenna after being connected with a reader, and the antenna layer 400 transmits electromagnetic waves with specific frequency. The strip-shaped antenna layer 400 enables the magnetic field to be uniformly distributed, and the big and small tags can be read within the radiation range of the antenna magnetic field.
