Fig. 2 is the schematic diagram of traditional built-in chip aerial mode.
Fig. 3 is the schematic diagram of embodiment of the handheld device of antenna integrated module of the present utility model.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The PCB radome is to utilize shield that components and parts, circuit or whole system are surrounded, and to outdiffusion, anti-locking system receiving circuit is subjected to external interference with the baffle system interference source.Simultaneously, the PCB radome also has physical protection and supporting role.Fig. 3 shows the principle of embodiment of the handheld device of antenna integrated module of the present utility model.The utility model can be to be applied to antennas such as GSM, CDMA, WiMAX, and present embodiment is to be example with the WiMAX antenna.See also Fig. 3, the circuit module that is positioned in the present embodiment on the PCB is divided into two parts, first is the sensitive circuit that is subject to outside electromagnetic interference, this part circuit is positioned at the bottom of PCB, adopt traditional metal material radome 2 (being exactly aforesaid PCB radome), second portion is the insensitive circuit that is not vulnerable to external interference thereby does not need electromagnetic shielding, this part circuit is positioned at the top of PCB, use non-electro permanent magnetic material (for example being plastic cement material) as radome 1, this plastic cement material radome 1 does not play electromagnetic shielding action, but has played physical shielding and antenna holder effect.So-called sensitive circuit generally comprises the radio circuits such as coupler, low noise amplifier, filter of RX path; So-called insensitive circuit generally comprises baseband circuits such as power management, SIM, USB, internal memory.Copper Foil 3 is attached to becoming antenna radiator above the plastic cement material radome 1, and the utility model is not limited to Copper Foil, can also be metal objects such as iron plate.The top of antenna radiator is stretched out antenna feed point and earth point downwards.
Also disclosed the embodiment of WiMAX Anneta module in the present embodiment, the WiMAX Anneta module is by as antenna radiator, its top is stretched out antenna feed point and earth point 4 downwards attached to the Copper Foil 3 on the non-electro permanent magnetic material radome (for example being the plastic cement material radome) (or being metal objects such as iron plate).
WiMAX adopts the 802.16e technology, requires system sensitivity to be-88dBm, now the technical development mainstream chip can accomplish sensitivity be-more than the 95dBm.Therefore, as long as antenna gain reaches in theory-7dB just can satisfy system's needs.
The elevator system performance also can highly improve plastic cement material radome 1 if desired, and this is equivalent to promote antenna radiator, and every lifting antenna radiator height 1mm can improve antenna efficiency about 10%.
