Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. 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 cable antenna includes an antenna body 100 and a feeder 200, and the feeder 200 is connected to one end of the antenna body 100 such that the feeder 200 radiates electromagnetic waves outward together with the antenna body 100. The antenna body 100 includes a PCB 300, a top antenna layer 400 and a bottom antenna layer 500, wherein a connection end plate 600 is disposed at an end of the PCB 300, the connection end plate 600 is used for connecting the antenna body 100 and the feeder 200, and specifically, the connection end plate 600 and the end of the feeder 200 are connected together by soldering, so that the antenna body 100 and the feeder 200 become a cable antenna.

Top layer antenna layer 400 is provided with the front of PCB board 300, and top layer antenna layer 400 is rectangular form, and its length is 100mm, and the width is 5mm, and length is less than the length of PCB board 300, and the width is the same width with PCB board 300. Bottom antenna layer 500 sets up the back at PCB board 300, and bottom antenna layer 500 is rectangular form for rectangular, and its length is 106mm, and the width is 5mm, and length is less than the length of PCB board 300, and the width is the same width with PCB board 300.

Antenna layers with specific length and shape are respectively arranged on two sides of the PCB 300, and the impedance of the antenna body 100 is adjusted to enable the frequency of electromagnetic waves radiated by the antenna body to be between 850MHZ and 950MHZ, and the electromagnetic waves belong to high-frequency radiation.

In order to increase the connection stability between the antenna body 100 and the feeder line 200, a PVC electric tape is wound on the outer side between the connection of the antenna body 100 and the feeder line 200. The PVC electric adhesive tape is prepared by coating a rubber type pressure-sensitive adhesive on a polyvinyl chloride film serving as a base material, and has the characteristics of good insulation, pressure resistance, flame retardance, weather resistance and the like.

The cable antenna that this embodiment provided is linear rectangular form, and is small, and occupation space is little, can follow the edge setting of access & exit. Some expensive special storage facilities in medical field also are fit for the installation of this cable antenna, only need with supplementary line or viscous substance with the cable antenna fix the edge of access & exit can, need not to change equipment itself, easy to assemble uses, the radiation directionality is strong moreover, the signal radiation distance can reach 3 meters.

In some special cases, it is desirable that the cable antenna has a specific radiation direction. For example, the cable antenna is installed at the edge of a door frame, and the cable antenna only needs to be radiated in the middle direction of the door in order to interfere with other surrounding objects or equipment by electromagnetic wave radiation.
