Area 162 and second surface 142 are distinguished.The area of first access area 161 and the second access area 162 can regard concrete condition setting,
When such as no setting is required on second surface 142 other structures, second surface 142 can be completely covered in the second access area 162.
The area of grounding parts 16 has an impact the radiance of radiator 13, the first access area 161 and the second access area
162 are capable of providing the area of bigger grounding parts 16, avoid and account in the concrete application of antenna module 100 because of other cablings
The limitation of grounding parts 16 workable for a part.
As shown in Fig. 2, antenna module 100 further includes lumped component 15, which is set to first surface 141 and connects
It is connected between radiator 13 and grounding parts 16, specifically can be and be serially connected between radiator 13 and the first ground branch 11.
For lumped component 15 for matching 100 input impedance of antenna module, the transmitting signal after making matching passes through radiator
13 to external radiation.Specifically, lumped component 15 can be Inductive component.
The inductance value of Inductive component is adjustable, to advanced optimize the adjusting to input impedance, and same size (radiation
The length of body 13) antenna module 100 can adapt to different products, improve the scope of application of antenna module 100
Feed line 17 is set to first surface 141 and is connected to radiator 13, is used for 13 input signal of radiator.Specifically
Ground, the feed line 17 can be set in side of the lumped component 15 far from the first ground branch 11, and it is practical new that this does not influence this
The implementation of type.
