Description
Technical field
The present invention relates to the communications field, specifically a kind of computer battery plate that built-in aerial is housed, reduce radiation, reduce the volume of antenna.
Background technology
Antenna is a kind of converter, and it is transformed into the guided wave of transmission above-the-line promotion to propagate in unbounded medium
electromagnetic wave, or carry out contrary conversion.?
radiobe used in equipment launching or receiving electromagnetic parts.Radio communication, broadcast, TV,
radar, navigation, electronic countermeasures, remote sensing, the engineering system such as radio astronomy, every electromagnetic wave that utilizes carrys out transmission of information, all relies on antenna to carry out work.
The range of application of present computer is more and more extensive, but brings puzzlement to the use of people in the problem of the frequent signal difference of computer always.Although existing built-in antenna does not see antenna at the outer surface of computer, there is the problems such as frequency range is very wide, Received signal strength weak effect in this type of built-in aerial mostly.People also more and more like portable, light and handy laptop computer, but bulky due to it, cause certain inconvenience.
Antenna is an important devices of concentrated reflection computer radiate performance.In recent years, panel computer obtains development at full speed, and panel computer antenna is tending towards multifrequency; Panel computer antenna often adopts Monopole antenna, although Monopole antenna is by the restriction of volume, specific absorption rate SAR and Specific Absorption Rate and human body sensing index are not particularly good always.Current SAR spoken of in the world, all for cellular mobile phone, be commonly called as the radiation that the Wireless Telecom Equipments such as mobile phone produce, namely under the effect of external electromagnetic field, induction field will be produced in human body, because the various organ of human body is lossy dielectric, therefore in body, electromagnetic field will generation current, causes absorbing and dissipative electromagnetic energy.The RF energy of antenna for mobile phone institute radiation can be absorbed by the body and produce heat, and is transmitted by the thermoregulatory system of human body.The definition of SAR is the ratio weighing human brain and absorption of human body or consumption electromagnetic power, that the how many radio frequency radiation energy of metering is by the representation unit of health institute actual absorption, be called special contribution ratios or claim SAR, representing with watt/every kilogram or milliwatt/every gram.The test of SAR is the radio wave energy produced via Wireless Telecom Equipment, measures human body actually by testing equipment, namely brain or body absorption how many electromagenetic wave radiations.And the induction index of panel computer test mainly refers to human body indicators, test mode is mainly the process that simulation people normally uses panel computer, allows panel computer press close to manikin, simulated human tissue liquid is housed inside manikin.Learn that panel computer is in real work by such test model, be absorbed by the body how many electromagenetic wave radiation energy.Standard international at present has two, and one is European standard 2w/kg, and one is Unite States Standard 1.6w/kg, and its concrete meaning refers to, with 6 minutes for timing, the electromagnetic radiation energy that per kilogram tissue absorbs must not more than 2 watts.Test through actual items finds, the SAR index of the panel computer of Monopole antenna form is easy to exceed standard.
The patent No. is that CN201789057U discloses a kind of Portable notebook computer antenna, and be one independently antenna, volume is little, effective, but radiation is large, also needs to carry constantly, also brings inconvenience.
The patent No. is that 202534780U discloses a kind of Low emissivity panel computer antenna, and radiation is little, but antenna mounting locations also needs to occupy certain space, for panel computer, increase its volume.
