Antenna device and intelligent communication equipment comprising same

Abstract

The invention discloses an antenna device and intelligent communication equipment comprising the same. The antenna device comprises: a conductive ink body which is used for being laid on an insulatingbase material in the intelligent communication equipment; a radiating element, wherein at least one part of the radiating element is formed by a conductive part, and the radiating element is arrangedon the periphery of the communication equipment and used for being coupled with the conductive ink body to generate low-intermediate frequency resonance; and a mainboard, wherein the conductive ink body or the radiation element is electrically connected to the mainboard. When the conductive ink body is electrically connected to the mainboard, the conductive ink body serves as a main radiator, andthe radiation element serves as a coupling branch knot. When the radiation element is electrically connected to the mainboard, the radiation element serves as a main radiator, and the conductive inkbody serves as a coupling branch knot. For the antenna device, a signal radiated by the main radiator can cover a medium-high frequency band; and, besides, current generated on the main radiator is coupled with the coupling branch knot, and coupled low-intermediate frequency resonance is generated, so that a signal is radiated, a medium-low frequency band is covered, and the antenna device achieves the effect of covering a full frequency band.

Description

technical field [0001] The present invention relates to an antenna device, in particular to an antenna device and an intelligent communication device containing it. Background technique [0002] With the development of science and technology, there are more and more functional requirements for smart wearable devices, and voice calls have become an essential function. Therefore, full-band antennas have become the basic configuration of smart wearable devices. The screen of a smart watch generally includes a screen glass (Lens) and a touch pad (TP). The touch pad is closely attached to the screen glass and is located below the screen glass. The area of ​​the touch pad is smaller than the area of ​​the screen glass. [0003] Due to the miniaturization and thinning of watches, the internal space of the watch is narrow and the antenna layout is limited. In the existing technology, the metal frame of the watch is often used as an antenna for radiation, and the main board is conne...

Problems solved by technology

[0003] Due to the miniaturization and thinning of watches, the internal space of the watch is narrow and the antenna layout is limited

In the existing technology, the metal frame of the watch is often used as an antenna for radiation, and the main board is connected to the metal frame through shrapnel. However, the metal frame of the watch is limited in length and cannot meet the performance requirements of the full-band antenna of 700MHz-960MHz and 1710MHz-2700MHz. In particular, it cannot meet the performance requirements of low-frequency antennas from 700MHz to 960MHz

[0004] In the prior art, the performance requirements are met by adding an antenna bracket inside the smart watch. However, due to the small internal space of the watch, it is often impossible to add an antenna bracket; On one side, the radiation absorption of the antenna by the arm affects the antenna efficiency
