Abstract

The invention provides a slotted waveguide antenna that can be laid in an existing space, effectively isolates signals which cannot reach isolation requirements and separately transmits the signals, and also provides a signal transmission device and a signal continuous transmission system that both comprise the slotted waveguide antenna. The slotted waveguide antenna is characterized by comprising at least one slotted waveguide tube for transmitting electromagnetic wave signals, wherein the slotted waveguide tube at least comprises a first pipeline and a second pipeline parallel to each other, the surface of each of the first pipeline and the second pipeline is equipped with multiple slots that enable the electromagnetic wave signals to be transmitted between the inside of each pipeline and the outside of each pipeline, and the first pipeline and the second pipeline are respectively used for transmitting two types of electromagnetic wave signals, wherein the frequency interval between the two types of electromagnetic wave signals cannot reach preset isolation requirements.

Description

technical field [0001] The invention relates to the field of wireless signal transmission, in particular to a slotted waveguide antenna capable of realizing continuous propagation of electromagnetic wave signals, a signal transmission device containing the slotted waveguide antenna, and a continuous signal transmission system. Background technique [0002] With the development of wireless technology, the application of wireless communication technology is becoming more and more extensive. In wireless communication systems, there are three main transmission methods for electromagnetic wave signals: antenna-based free wave transmission, leaky cable transmission, and cracked waveguide transmission. . [0003] The free wireless transmission method uses a directional antenna as the communication medium between the vehicle and the ground. It has less installation restrictions and is more convenient for installation and construction. However, the signal attenuation is faster, the c...
