Embodiment 1

[0065] see Figure 1~11 , an antenna conformal to the handle according to the present invention is used as an antenna of the narrowband Internet of Things (NB-IoT) as follows:

[0066] Wherein the dielectric gasket 4 is made of high temperature and corrosion resistant polyimide material. The working frequency band of the antenna is 866~918MHz (SWR is less than 1.5), taking into account the B5 frequency band (869~894MHz) of China Telecom and the B8 frequency band (880~915GHz) of China Mobile and China Unicom. The return loss characteristics of the antenna are shown in Figure 4 . The pattern of the antenna at a typical frequency point (890MHz) is as follows Figure 5 with Image 6 As shown, the pattern shows that the antenna has omnidirectional radiation characteristics. Due to the uncertainty of the relative position of the equipment terminal box and the base station, the antenna can effectively realize the communication between the equipment and the base station.

Abstract

The invention provides an antenna conformal to the handle, comprising: a radiator in the shape of a rod, one end of the radiator is rotatably installed on the outer wall of the door of an unattended terminal equipment box, and the other end of the radiator is bent Folded into the shape of the door handle of the radiator; the feeder cable is arranged inside the terminal equipment box, the inner conductor of the feeder cable is electrically connected to the radiator, and the outer conductor of the feeder cable is electrically connected to the terminal equipment box . The antenna can be multiplexed with the door handle on the door of the unattended equipment terminal box, that is, it serves as a handle structurally and as an antenna on the radio frequency to realize communication between the equipment terminal and the base station. Compared with the existing antenna scheme, the antenna has a low section height, high structural strength, and is installed with fasteners, so the structural reliability is strong; in terms of electrical performance, the antenna can achieve omnidirectional radiation, and introduces horizontal polarization components to improve the robustness of the communication system.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to an antenna conformal to a handle. Background technique [0002] With the development of a new generation of information technology, more and more industrial systems, mobile terminals, household appliances, vehicles and other equipment are connected to the Internet of Things, allowing people to implement remote control of equipment, which brings great benefits to production and life. Great convenience. [0003] For unattended terminal equipment, such as power distribution cabinets, hydrological monitoring stations, self-service printers, vending machines, etc., at present, universal antenna solutions are mostly used, that is, existing mature antenna products are purchased according to the working frequency band. [0004] After investigation, it is found that these devices basically use monopole or dipole antenna schemes. This form of antenna has the advantages of hig...
