Description
Technical field
The utility model relates to a kind of mobile phone, particularly a kind of clamshell phone.
Background technology
The develop rapidly of mobile communication in recent years, consumer is for the demand of communication terminal also in continuous increase, and mobile phone is the representative products of communication terminal.Along with user's use theory and the change of demand, the structure type of mobile phone, from early stage single board-type, has developed the Novel mobile phone construction such as flip-type and slide cover type.Particularly flip-type mobile phone, firmly gets consumer's favor with exquisite unique new ideas moulding, becomes one of main flow type of modern mobile phone.And the market demand makes modern mobile phone more and more trend towards the outward appearance of miniaturization, low section, corresponding, antenna for mobile phone also transfers by external antenna the earliest the built-in aerial that is hidden in hand set machine shell inside to; Meanwhile, conventionally can require the working frequency range of antenna for mobile phone at least can meet low frequency, two frequency ranges of high frequency, so that mobile phone can fully utilize low-frequency electromagnetic wave long transmission distance and the large feature of frequency electromagnetic waves carry information amount.
As in mobile phone conventional one type, as shown in Figure 1, the typical outward appearance of clamshell phone is that a body shell and one renovate housing, and two housings are flexibly connected by a rotating shaft.The inside of renovating housing is display screen mainboard, mainly supports the components and parts functions such as display screen, camera, receiver; And body shell inside is cell phone mainboard, the components and parts such as main set handling device chip, memory, battery tray, loud speaker, microphone are supported its corresponding function.The mainboard of two housings is electrically connected by a FPC flexible printed circuit board, and in order to prevent disturbing, positive and negative two outer surfaces of this FPC flexible PCB all arrange ground plane conventionally.
But because of cost control, for part liding machine, cell phone mainboard structure more and more modularization, become more meticulous, mainboard is usually designed to the form of " half plate ", the half that mainboard only has handset housing area even still less.This design causes mainboard too little, and affects the radio frequency reception function of mobile phone entirety.Antenna for mobile phone needs sufficient free space, need in the middle of motherboard layout, consider other components and parts dodging antenna.Antenna also needs to be controlled at the acceptability limit of international requirement for head part's radiation effect simultaneously.In view of this, the present generally lowermost end in housing by the Antenna Design of clamshell phone of cellular telephone companies.Can either reduce motherboard layout like this time, in order to consider the design constraint of antenna performance, ensure the free space of antenna, also increased the distance between the number of people and antenna, reduced the risk that antenna exceeds standard to human body radiation.But in the time of the lowermost end of Antenna Design at flip-type mobile phone, produce a bad problem: be while uncapping use state low-frequency range (for example GSM850 of antenna at mobile phone; GSM900; CDMA800) performance can sharply worsen, and causes the radiant power of mobile phone and receiving sensitivity all to decline to a great extent.This is because the antenna of mobile phone generally adopts unbalanced antennas, and in this case, the ground of cell phone mainboard can not be considered as desired reference ground, and the ground of cell phone mainboard is not reflector but radiant body itself is also a part for antenna, participates in aerial radiation yet.The meetings such as shape, size and the connected mode on cell phone mainboard ground cause appreciable impact to antenna performance.According to the radiation mechanism of quarter-wave aerial, the low-frequency range radiance of antenna for mobile phone is especially subject to the impact on mainboard ground, and ground is an important radiant body of low-frequency electromagnetic wave.Generally, the low-frequency range radiation pattern of antenna for mobile phone is similar to the radiation pattern of half-wave dipole antenna; And if antenna for mobile phone design is at the lowermost end of housing, be while uncapping use state at mobile phone, the radio-frequency current of the ground of cell phone mainboard is in the time of the FPC by connecting display panel and cell phone mainboard, the radiation pattern of meeting heavy damage antenna low-frequency range, make radiation pattern become disorderly and unsystematic, thereby cause the deterioration of antenna low-frequency range radiance.
Therefore mobile phone antenna performance depends on the radio frequency environment of mobile phone itself.The length of cell phone mainboard is larger on low-frequency range impact, and the width of mainboard is larger on high band impact.If main board length deficiency, causes antenna for mobile phone useful space deficiency, antenna efficiency will be low.And as the cell phone mainboard ground of the part of antenna radiator, its length is especially particularly important on the impact of small size mobile phone.
