Problems solved by technology
[0002] In the tunnel, the environment is complex, and the wireless signal undergoes multiple reflections and diffractions, which greatly reduces the transmission distance of the wireless signal and the coverage ability. Ordinary back-firing antennas generally face one direction and have strong directivity, but they cannot realize the transmission of the tunnel. All-round wireless coverage in this environment

The invention discloses an underground tunnel remote signal coverage high-gain antenna and a manufacturing method thereof. The high-gain antenna comprises a reflector. The reflector is equipped with aterminal. A feeder line connected to the terminal is led out from the reflector. The outer surface of the reflector is provided with a plurality of rhombus structures formed by oscillators. The rhombus structures are connected with the feeder line through the terminal. The reflector reflects wireless signals irradiating thereof to the oscillators; the oscillators reflect and receive the wirelesssignals as feed sources; and the feeder line transmits the signals reflected by the oscillators as a transmission line. The antenna is simple in structure, small in size and far in signal propagationdistance, and is especially suitable for linear occasions of tunnels and pipe ditches and the like.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to an underground tunnel long-distance signal coverage high-gain antenna and a manufacturing method thereof. Background technique [0002] In the tunnel, the environment is complex, and the wireless signal undergoes multiple reflections and diffractions, which greatly reduces the transmission distance of the wireless signal and the coverage capability. Ordinary back-firing antennas generally face one direction and have strong directivity, but they cannot realize the transmission of the tunnel. This environment provides full wireless coverage. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a long-distance signal coverage high-gain antenna for underground tunnels. The present invention has a simple structure, and can realize directional radiation of wireless signals, and the radiation distance is long. It is es...
