Embodiment
See also Fig. 1 and Fig. 2, the invention provides a kind of Anneta module 100, be installed in mobile phone, personal digital assistant (personaldigitalassistant, etc. PDA) in radio communication device, and carry out launching, receiving radio wave with radio signals in multiple frequency range.
This Anneta module 100 comprises carrier 10 and antenna 20.This carrier 10 is for carrying this antenna 20.The roughly rectangular cover body shape of this carrier 10, comprises the loading end 11 of level, the side 12,13,14 that be connected vertical with this loading end 11.This loading end 11 surrounds a roughly rectangular holding part 15 jointly with this side 12,13,14, for accommodating HDMI (High Definition Multimedia Interface) (HighDefinitionMultimediaInterface, HDMI) metal device such as connector, USB (UniversalSerialBUS, USB) connector, loud speaker.The medium position of this loading end 11 offers roughly rectangular opening 111, and this opening 111 communicates with this holding part 15.
This antenna 20 is a single-polarized antenna, and the lamellar body be made up of electric conducting materials such as metals is made.This antenna 20 comprises the first radiating element 21, second radiating element 22, resonating member 23, feed-in unit 24 and ground unit 25.
This first radiating element 21 is arranged along the marginal position of this loading end 11 near side 12, and part is laid on this side 12,13, for inspiring a corresponding low frequency modal.In order to obtain better LF communication quality, as shown in the figure, the terminal end width of the first radiating element 21 also can suitably increase.
This second radiating element 22 is connected with this first radiating element 21, and extends along the direction away from this first radiating element 21, and part is laid on the another side 14 adjacent with this side 12.The length of this second radiating element 22 is less than the length of this first radiating element 21, for inspiring a corresponding high frequency mode.
This resonating member 23 is a strip lamellar body, is wholy set on this loading end 11, for inspiring a corresponding high-frequency resonance mode.This resonating member 23 and this second radiating element 22 are arranged at the same side of this first radiating element 21, and consistent with the bearing of trend of this second radiating element 22 also structure is at a certain angle.The length of this resonating member 23 is less than the length of this second radiating element 22.
This feed-in unit 24 is roughly in hook-shaped, be connected with this first radiating element 21 and the second radiating element 22, and extend along the direction away from this second radiating element 22, and through bending, to pass this opening 111, and then be obliquely extended in the plane opposing with loading end 11, to hold the sidewall of this opening 111.This feed-in unit 24 is electrically connected with the traditional Signal transmissions end (not shown) be arranged on the circuit board of radio communication device inside, thinks that described Anneta module 100 plays signal feed-in effect.
This ground unit 25 is connected to the end of this resonating member 23, and be arranged in parallel with this feed-in unit 24.The shape of the shape of this ground unit 25 and structure and this feed-in unit 24 and structure quite, do not repeat them here.This ground unit 25 can be connected with the traditional grounded part on circuit board, thinks that described Anneta module 100 provides ground connection to act on.
Refer to Fig. 3, what be depicted as inventive antenna module 100 returns loss (returnloss, RL) measurement result schematic diagram.Can find out by figure, this Anneta module 100 can be contained to multiple communication system such as GSM850, EGSM900, DCS1800, PCS1900, WCDMAI, WCDMAII, WCDMAIV, WCDMAV and WCDMAVIII.
Refer to table 1, be depicted as the average efficiency of inventive antenna module 100.As shown in Table 1, this Anneta module 100 all meets Antenna Operation designing requirement in average efficiency.
The average efficiency of each frequency of table 1 Anneta module
Obviously, Anneta module 100 of the present invention is by moving to the medium position of described carrier 10 by described feed-in unit 24 and ground unit 25 from the side of traditional carrier 10, namely the back side of the various metals devices such as described HDMI connector, USB connector is moved to, to deviate from these metal devices, obtain preferably isolation effect, and then effectively improve the radiation efficiency of this Anneta module 100.In addition, this Anneta module 100, by arranging this resonating member 23, to inspire corresponding resonance mode, effectively widens high frequency and the low-frequency range of Anneta module 100, makes Anneta module 100 can possess enough wide signal transmitting and receiving frequency.
