Problems solved by technology

In PCB communication technology, the usual exciter is an antenna, and the signal wave usually emitted by the antenna is an electromagnetic wave (abbreviated as TEM wave) in the transverse electromagnetic field (transverse electric and magnetic field, TEM) mode. However, the energy of the TEM wave during transmission The attenuation is large, so there is an urgent need for an exciter that can emit electromagnetic waves with low attenuation characteristics

Embodiment Construction

[0041] With the development of PCB communication technology, the amount of communication data continues to increase, which puts forward higher requirements for data transmission efficiency. In the traditional PCB communication system, the signal wave emitted by the exciter used to transmit the signal is usually the TEM wave. Transmission through the transmission line can only be transmitted in space through the air medium. Therefore, the energy of the TEM wave is greatly attenuated during transmission.

[0042] The embodiment of the present application proposes an exciter capable of emitting surface waves. The surface waves refer to electromagnetic waves transmitted along the interface of different media. For example, the interface of different media may be the surface of a PCB transmission line (abbreviation: transmission line), Therefore, the energy attenuation of the surface wave is small during transmission. The surface wave may be formed by electromagnetic waves in Trans...

Abstract

The invention provides an exciter and a printed circuit board communication system, and relates to the technical field of communication. The exciter comprises a PCB antenna (101) and a mode conversionstructure (102). The PCB antenna (101) is configured to emit transverse electromagnetic field TEM waves; the mode conversion structure (102) is located on the side where the beam transmitting end ofthe PCB antenna (101) is located; the mode conversion structure (102) is configured to receive the TEM waves, convert the TEM waves into surface waves and then output the surface waves. According to the invention, the problems of low data transmission efficiency and large signal loss of signal waves at the bent part of the transmission line can be solved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular, to an exciter and a printed circuit board communication system. Background technique [0002] A printed circuit board (printed circuit board, PCB) communication system refers to a communication system applying the PCB communication technology. The PCB communication system at least includes: an exciter and a receiver arranged on the PCB. The PCB communication technology refers to the communication technology in which the exciter transmits the emitted signal wave to the receiver through the PCB. With the development of PCB communication technology, the amount of communication data continues to increase, which puts forward higher requirements for data transmission efficiency. In PCB communication technology, a common exciter is an antenna, and the signal wave emitted by the antenna is usually an electromagnetic wave in a transverse electric and magnetic field (T...
