Description of drawings
Fig. 1 is a kind of structural representation that antenna is set in phone housing of the embodiment of the invention;
Fig. 2 is the another kind of the embodiment of the invention is provided with antenna in phone housing a structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.Following examples are used to explain the present invention, but are not used for limiting scope of the present invention.
Present embodiment is that example describes RF receiving/transmission device is arranged on the phone housing, and the RF receiving/transmission device of present embodiment comprises antenna.Through radio-frequency antenna being arranged in the phone housing realizing external antenna, and phone housing is detachable the connection with mobile phone body.As shown in Figure 1, the portable terminal external antenna of this enforcement comprises: mobile phone ectosome 1, be arranged on the antenna 2 on the phone housing 1, antenna 2 be provided with mobile phone in the contact interface 21 (being not limited to contact, can also be plug-in type) that is connected of mainboard.Antenna 2 is the antenna of one-segment or multiband.In design during mobile phone, make load onto phone housing 1 back contact formula interface 21 just in time with mobile phone in power amplifier on the mainboard contact, make mobile phone adapt to the frequency range of these antenna 2 correspondences.When the user is in the various network frequency range; Travel abroad like the user; As shown in Figure 2; Can change a phone housing 3 that includes the radio-frequency antenna that adapts to this national network frequency range, this phone housing 3 is provided with the antenna 4 that adapts to this national network frequency range, antenna 4 be provided with mobile phone in the contact interface 41 that is connected of mainboard.Realized like this realizing the more method of switching network frequency range through changing phone housing.Antenna is installed in the terminal enclosure, and is equipped with different shells to the network environment of country variant, the user through changing terminal enclosure, can satisfy the heterogeneous networks needs when international roaming like this.
Only antenna is arranged on the phone housing in the present embodiment; Still place on the inner mainboard of mobile phone with the corresponding power amplifier of antenna, filter and radio frequency chip; In order to adapt to the antenna of different one-segment or simple frequency range stack; Power amplifier, filter and radio frequency chip remain power amplifier, filter and the radio frequency chip of supporting full frequency band, and mobile phone thickness is still thicker.
Present embodiment is a preferred embodiment, and in the present embodiment, RF receiving/transmission device comprises antenna, power amplifier, filter and radio frequency chip.Be about to power amplifier, filter and radio frequency chip and be set on the phone housing together with antenna, antenna is the antenna of one-segment or multiband, and power amplifier, filter and radio frequency chip all are complementary with one-segment or multiband.Radio frequency chip be provided with mobile phone in the mainboard contact or the plug-in type interface that are connected.In design during mobile phone, make load onto phone housing after, contact interface or plug-in type interface just in time with mobile phone on the mainboard corresponding interface contact, make mobile phone adapt to the frequency range of this antenna correspondence.
Because antenna, power amplifier, filter and radio frequency chip are not to support full frequency band, device volume is less, thereby has reduced mobile phone thickness, has also reached simultaneously to change the purpose that phone housing makes mobile phone adaptation heterogeneous networks frequency range.
Wherein, RF receiving/transmission device also can include only antenna and power amplifier, is about to antenna and power amplifier and is set on the phone housing, and filter and radio frequency chip still are arranged on the cell phone mainboard.Power amplifier be provided with portable terminal in the interface that is connected of main on-board filter.
