Embodiment Construction

[0033] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0034] The invention discloses a full-band high-gain antenna 3-5 applicable to 2G, 3G, and 4G communications at the same time, such as figure 1 As shown, the design of the antenna is based on the actual environment of the tunnel site to increase the radiation range of the antenna signal. By setting a specific length of the radial part of the antenna, combined with the installation method of the antenna in the present invention, the signal can effectively penetrate the outer cast iron manhole cover, to achieve signal strength externally receivable.

[0035] The antenna is a 1 / 4λ antenna, which can work in the frequency bands of 2G, 3G, and 4G communication at the same time. The antenna mainly includes: SMA male connector 1-1 (SMA-J5, internal thread internal needle), SYV-50-3 with Axial radio frequency cable 1-4, copper tube 1-3, RG316 coaxial...

Abstract

The present invention proposes a full-band high-gain antenna and device suitable for 2G, 3G, and 4G communications, including: SMA connector, SYV-50-3 coaxial radio frequency cable, copper tube and antenna feeder; coaxial radio frequency The copper core of the cable is welded on the SMA male connector; the copper tube is sleeved on the coaxial RF cable, and the distance between the copper tube and the metal tail of the SMA male connector is kept at a set distance M; the antenna feeder passes through the SMA female The cooperation between the connector and the SMA male connector realizes the electrical signal connection between the antenna feeder and the SYV‑50‑3 coaxial RF cable. The antenna of the present invention overcomes the disadvantage of large antenna size under high-gain conditions; solves the limitations of 2G, 3G, and 4G signal coverage in the external environment of different engineering sites, and realizes the simultaneous application of 2G under the cast iron manhole cover in a limited space , 3G, 4G full-band antenna for communication.

Description

technical field [0001] The invention relates to an antenna device, in particular to a full-band high-gain antenna installed on a second-layer sub-cover and applicable to 2G, 3G, and 4G communications under shielding conditions in a tunnel cast iron well. Background technique [0002] Urban power tunnels are widely distributed, and many remote areas have different 2G, 3G, and 4G signal strengths. Especially in the shielding environment under the cast iron manhole cover, the wireless module installed on the second-story sub-cover under the cast iron manhole cover transmits signals, and it is difficult to be detected. Effective and stable reception. In order to ensure the safety of communication and power supply of the underground pipe corridor, it is very necessary to obtain a stable communication transmission signal of the monitoring information of the intelligent monitoring manhole cover through the antenna, and upload it to the network platform outside the tunnel in real ti...
