Description
Technical field
The utility model relates to a kind of built-in dual-band mobile phone antenna, refers in particular to the antenna for mobile phone based on slit, comb type floor of a kind of 1920-2170MHz of working in and 2.4GHz.
Background technology
Along with the arriving in mobile communication epoch, mobile phone has become the individual and has carried, used one of indispensable communication articles for use.Wherein, antenna for mobile phone is the necessary part that realizes cell-phone function, and the quality of antenna performance greatly influences the communication quality of mobile phone.Under the prerequisite that does not reduce its usefulness, antenna for mobile phone develops towards direction light, thin, short, little, double frequency/multifrequency as much as possible.The main flow antenna that is applied to mobile phone at present mainly is built-in microstrip antenna.
Built-in microstrip antenna is to utilize to be carved with metal micro-strip paster and ground plate on the medium substrate and to come electromagnetic signal is produced resonance.Advantages such as the type antenna has low profile, in light weight, flexible design, processing technology maturation, processing is simple, cost of manufacture is low, but the type antenna has the common drawback of microstrip antenna: narrow bandwidth.Be subjected in the built-in aerial size under the condition of the strict restriction in mobile phone space, spread bandwidth is then more difficult as far as possible, in order to overcome this shortcoming, people adopt the increase dielectric substrate thickness, increase parasitic patch, adopt methods such as multilayer dielectricity substrate and paster to come spread bandwidth, these are improved one's methods and have increased the antenna cumulative volume undoubtedly, and it is more difficult to make it to be placed on the mobile phone inside that layout is compact day by day, the space is crowded day by day.Appearance along with multifunction wireless communicating terminal products such as smart mobile phone, multimedia handsets, mobile phone carrying function more and more, required parts also increase thereupon, and it is more and more littler that this makes mobile phone inside leave the space of built-in aerial for, and built-in aerial small size and wide band contradiction are also more outstanding.Therefore, people have carried out corresponding improvement to built-in microstrip antenna, and what application potential was wherein arranged most is planar inverted-F antenna.But the planar inverted-F antenna of existing GSM of working in and DCS frequency range generally has 6 to 10mm thickness, this need place thickness between microband paste and ground plate be 6 to the dielectric-slab of 10mm, this has increased the volume and weight of entire antenna undoubtedly, limited such antenna in the applications that thickness is had strict demand, also developed contradicting to light, thin, little direction with mobile communication terminal.
Increasingly mature along with 3G (Third Generation) Moblie market, the particularly propelling of the commercialization of WCDMA network technology, market will be more and more urgent to the demand of the antenna for mobile phone that works in this frequency range.Simultaneously, people are also more and more to the demand of mobility visit and stored information, and it is urgent that the market demand of WLAN (WLAN (wireless local area network)) also more seems.The advantage of WLAN (wireless local area network) do not need to be cable laying or optical cable just can visit existing computer network, and the WLAN frequency range is free frequency spectrum, 802.11b the message transmission rate of standard reaches 11M, 802.11g reach 54M, be far longer than the message transmission rate of existing mobile communications system, superiority bandwidth is fairly obvious.The function of WLAN being integrated in the middle of the portable terminal of relatively popularizing now is a developing direction of Large Volume Data communication.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of can be simultaneously in 1920-2170GHz and the work of 2.4GHz two-band, and have broadband, low profile, size is little, in light weight, cost is low, structure and processing technology be simply based on the built-in mobile phone antenna in slit, comb type floor.
Principle of the present utility model is: adopt the technology of microband paste being carried out capacitive load, reduce the height of planar inverted-F antenna, and adopt the design philosophy that ground plate cracks further to reduce the antenna overall dimensions, and keep radiance preferably, make it to be fit to be applied to mobile phone inside.On the other hand, the method of the utility model by cracking simultaneously at microband paste and ground plate, enlarge the beamwidth of antenna, increase the resonance point of antenna, make it to work in simultaneously WLAN (wireless local area network) (2.4GHz) frequency range and 3G (Third Generation) Moblie (WCDMA) frequency range of present extensive use.
