Abstract

The invention provides a magnetic rod antenna. The magnetic rod antenna comprises a magnetic rod and a wire, wherein a plurality of parts of the wire are sequentially wound around the magnetic rod to form a plurality of coils in an alternately sparse and dense manner, and the magnetic field intensity of the plurality of coils laminated on division magnetic fields of respective cross section of the same magnetic rod is higher than the magnetic field intensity of the total magnetic field of the coil formed by uniformly winding the existing wire around the magnetic rod. The magnetic rod antenna provided by the invention is longer in signal transmission distance, and is not susceptible to the interference of an outside environment; and moreover, with the magnetic rod antenna provided by the invention, the magnetic flux of the antenna can be improved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a magnetic rod antenna. Background technique [0002] In engineering construction, it is often necessary to penetrate the ground to transmit the collected signals from the ground to the surface through wireless transmission, and then restore and analyze them through surface instruments such as handheld instruments. [0003] In modern communication technologies, WiFi, Bluetooth, ZigBee, etc. cannot be used because they cannot penetrate thick barrier layers. The traditional 1k ~ 100kHz electromagnetic wave is easier to penetrate the formation when it is emitted by a magnetic rod antenna, but its penetration distance is limited and it is easily disturbed by the external environment. With the acceleration of urbanization and the complexity of pipe network layout, trenchless construction has expanded from the initial 10 meters underground to 20 to 30 meters. Therefore, ther...
