Description of drawings
Fig. 1 is the structural representation of antenna for mobile phone.
Embodiment
Flourish along with radio communication, many communication tools all are tending towards miniaturization, in order to meet this demand, some built-in antenna volume also require little, and for example inverted F-type flat plane antenna (PIFA) has near isotropic radiation characteristic and the little advantage of volume.Antenna for mobile phone disclosed in this invention has the advantage of inverted F-type flat plane antenna (PIFA), but also does not take the mobile phone volume inside, has satisfied the miniaturization of mobile phone and the requirement of feature richness.
Structural representation and preferred embodiment below in conjunction with accompanying drawing 1 antenna for mobile phone are described in detail antenna for mobile phone of the present invention.
Antenna for mobile phone of the present invention comprises metal level 1, earthing device 5, feeder means 6, and simultaneously, metal level 1 is by groove 7 zoning territories.The material of metal level 1 can be selected metal materials such as stainless steel, magnesium alloy, aluminium alloy for use.Earthing device 5 is connected with zero potential, is used for providing earthed voltage to antenna for mobile phone.Earthing device 5 is a spring pressuring plate among the present invention, can realize easily that the zero potential of the printed circuit board (PCB) of antenna for mobile phone and mobile phone reliably is connected, and has also made things convenient for the installation of mobile phone simultaneously.Metal level is provided with feeder means 6, can partly be connected with the RF of printed circuit board (PCB) in the mobile phone, is used to receive and dispatch radio frequency.By feeder means 6, can realize the signal transmission between antenna for mobile phone and the mobile phone, realize reception and the emission of mobile phone to wireless signal.Feeder means 6 is a spring pressuring plate among the present invention, can realize easily that the reliable of printed circuit board (PCB) of antenna for mobile phone and mobile phone is connected, and has also made things convenient for the installation of mobile phone simultaneously.Groove 7 is divided into several regions with metal level 1, and the area of adding metal level is big, makes antenna for mobile phone can satisfy the requirement of different frequency bands to antenna size like this, makes antenna for mobile phone can receive or send the wireless signal of different frequency bands.When this antenna for mobile phone is applied to mobile phone, because metal level 1 is divided into different zones by groove 7, the button that can this zone be set to cell phone keyboard, for example can be set to common key-press 4 in some zone, be used to be provided with numerical key or function key, can also be set to direction button 3 by some functional area, the operation that is used to control mobile phone enters different functions.For the operation of convenient control mobile phone, can also be provided with side switch 2 at metal level, enter some specific function of mobile phone fast by side switch 2.
Below built-in aerial formula mobile phone of the present invention is described in detail.Built-in aerial formula mobile phone of the present invention is the improvement to original mobile phone, the inverted F-type flat plane antenna (PIFA) of original mobile phone is replaced with the antenna for mobile phone that has metal level 1, antenna for mobile phone and cell phone keyboard are integrated, make the mobile phone inner space more abundant, setting brings great convenience to structure, like this, solved the contradiction of cell-phone function and mobile phone miniaturization.
The antenna for mobile phone of built-in aerial formula mobile phone of the present invention is used to receive and dispatch radio frequency, comprises metal level 1, earthing device 5, feeder means 6, and simultaneously, metal level 1 is by groove 7 zoning territories.Earthing device 5 is connected with the ground plane of mobile phone printed circuit, is used for providing earthed voltage to antenna for mobile phone.Earthing device 5 is a spring pressuring plate among the present invention, can realize easily that the ground plane of the printed circuit board (PCB) of antenna for mobile phone and mobile phone reliably is connected, and has also made things convenient for the installation of mobile phone simultaneously.Feeder means 6 partly is connected with the RF of the printed circuit board (PCB) of mobile phone.By feeder means 6, can realize the signal transmission between antenna for mobile phone and the mobile phone, realize reception and the emission of mobile phone to wireless signal.
Feeder means 6 is a spring pressuring plate among the present invention, can realize easily that the reliable of printed circuit board (PCB) of antenna for mobile phone and mobile phone is connected, and has also made things convenient for the installation of mobile phone simultaneously.Groove 7 is divided into several regions with metal level 1, make antenna for mobile phone can satisfy the requirement of different frequency bands like this to antenna size, make antenna for mobile phone can receive or send the wireless signal of different frequency bands, thereby make mobile phone can receive and launch the wireless signal of different frequency bands.Metal level 1 made full use of the cell phone keyboard area big, apart from the characteristics of printed circuit board (PCB) distance, satisfied of the requirement of PIFA antenna for the space.Because metal level 1 is divided into different zones by groove 7, the button that can this zone be set to cell phone keyboard, for example can be set to common key-press 4 in some zone, be used to be provided with numerical key or function key, can also be set to direction button 3 in some zone, the operation that is used to control mobile phone enters different functions.For the operation of convenient control mobile phone, can also be provided with side switch 2 at metal level, enter some specific function of built-in mobile phone fast by side switch 2.
Because the battery of built-in mobile phone can exert an influence to antenna for mobile phone, specifically, battery of mobile phone can reduce the resonance frequency of antenna for mobile phone, can reduce the efficient of antenna for mobile phone simultaneously, therefore preferably battery of mobile phone is placed on the position away from antenna for mobile phone, distance should be greater than 5mm.Among the present invention, metal level 1 and battery of mobile phone should be arranged on the same side of printed circuit board (PCB), and the distance between metal level 1 and the battery of mobile phone is greater than 5mm.
