Problems solved by technology

[0005] The invention provides a strong penetrating antenna device buried in reinforced concrete, which is used to solve the problem that the passive tag chip is in a harsh electromagnetic propagation environment (such as when it is built in a concrete structure) and cannot be connected to the outside world through a cable. In the case of the technical problem of communicating with the outside world through the antenna, the technical solution is as follows:

Abstract

The invention provides an antenna device with excellent penetrating performance. The antenna device includes a first radiator, a second radiator, a third radiator, and a dielectric substrate. The slotof the first radiator is configured to adjust the antenna impedance to achieve an effect of adjusting the resonance frequency. The dielectric substrate with a corresponding dielectric constant is arranged between the first radiator and the second radiator as required. The third radiator is used as a reflection plate, is located below the second radiator and increases the gain in the direction of0-degree angle. A low-dielectric-constant medium with a certain thickness is disposed directly above the first radiator. A feeding point is disposed on the first radiator. The second radiator is grounded. The antenna device has excellent penetrating performance, and can still smoothly transmit energy to the outside when buried in reinforced concrete.

Description

technical field [0001] The invention relates to an antenna electronic device, in particular to a strong penetrating antenna device. Background technique [0002] Most of the antennas are applied in free space or on the surface of objects. Specifically, the antennas of most electronic devices are applied in the air, and some electronic devices are placed on walls, metals, skin surfaces, etc. In short, electronic equipment will be in contact with the air in one direction, which is conducive to the transmission of electromagnetic wave energy. Corresponding research papers on free-space antennas account for the vast majority. Few research papers on antenna design for harsh electromagnetic propagation environments can be retrieved. [0003] The harsh electromagnetic propagation environment has effects such as attenuation, reflection, and scattering on electromagnetic waves. When electronic equipment is placed in such an environment such as reinforced concrete, it is difficult f...
