Antenna structure and wireless transmission device

Abstract

The present application relates to an antenna structure and a wireless transmission device. The antenna structure includes a first antenna component, a second antenna component and a connection component; the first antenna component is provided with at least one first feeding terminal and at least one first ground terminal, each The first feed terminal and each first ground terminal are used to vertically install the first antenna assembly on the substrate; the second antenna assembly is provided with at least one second feed terminal and at least one second ground terminal, and each second The feeding terminal and each second grounding terminal are used to vertically install the second antenna component on the substrate; the connecting component is respectively connected to the grounding terminals of the first antenna component and the second antenna component. On the one hand, it overcomes the technical prejudice that those skilled in the art think that the two antenna components of the antenna should not be electrically connected, realizes the effective transmission of wireless signals, and has the advantages of simple structure and convenient implementation; on the other hand, it is beneficial to reduce the size of the two antennas The spacing between components improves the applicability to miniaturized products.

Description

technical field [0001] The present application relates to the field of antennas, in particular to antenna structures and wireless transmission devices. Background technique [0002] An antenna (antenna) is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, usually free space, or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The antenna conforms t...

[0005] The other is vertical, such as figure 2 As shown, the two antenna assemblies 101 are vertically arranged on the substrate 200. In this antenna layout, the two antenna assemblies 101 are separated. This design will make the assembly of the wireless terminal particularly difficult, because each It is very time-consuming to weld each antenna separately, and because the entire antenna still has a medium, the characteristics of the antenna are still not good enough, and the medium will inevitably affect the transmission and reception of signals by the antenna.

[0006] It is worth pointing out that those skilled in the art generally believe that the two antenna components of the antenna should not be electrically connected, otherwise it will seriously affect the characteristics of the antenna and even fail to realize the transmission and reception of signals; and there are also requirements for the distance between the two antenna components. However, in order to adapt to the smaller size in specific applications that require extremely small PCB space, the minimum distance between the two antenna components is usually less than half a wavelength, and the closer the two antenna components are, the stronger the mutual influence
