Embodiment Construction

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Self-resonant array antenna embodiment 1

[0029] like figure 1 , figure 2 As shown, a self-resonant array antenna includes first and second antenna units, and each antenna unit is composed of an AC loop and an excitation loop.

[0030] For the first antenna unit, its AC loop is a capacitive loading coil 105 , and two ends of the coil are connected through a single capacitor 106 . Capacitors use low loss capacitors. Coil 105 is a turn of ribbon (or bar) conductor. The excitation loop 107 is surrounded by the coil 105 to form a conductive ring, and the open end 101 of the conductive ring is connected to the transmit / receive port 103 of the through-the-earth communication system 104 via a wire.

[0031] For the second antenna unit, its AC loop is a capacitive loading coil 108 , and two ends of the coil are connected through a single capacitor 109 . ...

Abstract

The invention relates to a self-resonant array antenna for through-the-earth communication and an antenna unit. The array antenna comprises at least two antenna units; each antenna unit includes an alternating-current loop and an excitation loop; the alternating-current loop comprises a coil which is formed by at least one turn of electric conduction body and a capacitor module which is connected between two ends of the electric conduction body; the excitation loop comprises an electric conduction ring, wherein the electric conduction ring has an open end which is used for connecting a signal transmitting or receiving port of a communication system; the alternating-current loop and the excitation loop in the same antenna unit are in insulation and electromagnetic field coupling with each other; and the open ends of the excitation loops of the antenna units are in series connection, in parallel connection or in series-parallel connection. With the self-resonant array antenna of the invention adopted, the ability of the through-the-earth communication system to receive weak signals can be significantly improved, and therefore, the problem of short through-the-earth communication transmission distance can be solved.

Description

technical field [0001] The present invention relates to the field of through-the-ground communication, in particular to a self-resonant array antenna and an antenna unit as the main constituent part of the array antenna. Background technique [0002] When a mine disaster occurs, the conventional wired communication system is usually destroyed. The interruption of communication between the underground and the ground directly causes the survivors trapped in the underground to be unable to contact the ground personnel or ambulance personnel, which brings great difficulties to timely and effective rescue. . [0003] The stratum of the mine is mainly composed of a multi-layered structure composed of sedimentary rocks. Each layer belongs to different layers. Each layer has several mineral layers and surrounding rocks, which makes the transmission conditions of wireless signals in the strata very complicated. However, the earth channel is relatively stable and is generally not aff...
