Problems solved by technology

[0010] Ordinary built-in antennas have the characteristics that the lower the receiving frequency, the larger the volume required, and the frequency range of 470MHz-700MHz required to realize mobile TV is relatively low in the receiving frequency of the antenna, and it is common to receive such frequencies The built-in antenna of a mobile phone or a handheld computer requires a large volume, and the layout of a mobile phone or a handheld computer is compact and the space is small, so it is very difficult to install a large-sized built-in antenna

Abstract

The invention provides a low frequency built-in aerial for a hand-held communication device comprising a radiation body respectively arranged on each layer of the multi-layer PCB boards. The low frequency built-in aerial for the hand-held communication device provided by the invention applies the multi-layer PCB board technology on the aerial design, uses the characteristic of the compact and low volume of the PCB board, performs the aerial radiation design on each layer, thereby guaranteeing a smaller volume of the built-in aerial device. Moreover the radiation body is mainly in the internal layer of the PCB, the final design of the aerial radiation body has a certain concealment, and is difficult to copy and produce. The stacked coupling compresses the aerial size by pressing convention. In a limited space, the invention designs the aerial by full volume and reaches best aerial property.

Description

technical field [0001] The invention relates to antenna technology, in particular to a low-frequency built-in antenna for handheld communication equipment. Background technique [0002] Watching TV for free on mobile phones or handheld computers has always been something that many consumers have been looking forward to for a long time. At present, with the mobile TV playing free cards, this wish is expected to be realized in 2008. On June 9, the holder of the basic patent of the domestic mobile TV industry standard announced that the patent for Mobile Multimedia Broadcasting (CMMB) will be completely free for the next two years, and a symbolic patent royalty of 1 yuan will be charged thereafter. This means that the industry standard CMMB for mobile multimedia broadcasting has entered the stage of commercialization. [0003] "Mobile TV service" refers to the service of watching TV on a smart phone with operating system and video function. [0004] The CMMB standard is a mo...
