It is low, and can directly weld together with PCB circuit board.PIFA antenna is day built in the mobile phone that is most widely used at present
Line, have it is light-weight, size is small, section is low, low cost, mechanical strength are good, bandwidth, high-efficient, high gain, by ring around
Border influences the series of advantages such as small, small to human body radiation injury, covering frequence is more.
Optionally, as shown in figure 4, the antenna 206 specifically may be that inverted L-shaped pcb board carries antenna, relative to PIFA days
Structure is more simple for line.
Optionally, the antenna 206 specifically or spring antenna, spring antenna according to material can be divided into nickel plating, it is gold-plated,
Copper spring antenna, according to frequency it is general it is common have 315/490/868/915MHz spring antenna, select spring antenna when
It waits, the parameters such as size length, gain, impedance, material, frequency, standing-wave ratio can be selected to meet demand according to actual items demand
Spring antenna.
Optionally, the purposes for being directed to the wireless communication module is different, is such as used for Wifi connection, bluetooth connection or ZigBee
Connection, the communication chip 202 are specifically as follows Wifi chip, Bluetooth chip or ZigBee chip.
Optionally, die terminals match circuit 203 and antenna end match circuit 204 mentioned herein are specifically as follows π type
With circuit, the embodiment of the present application is realized by placing two π type match circuits in feeder part to die terminals and antenna
End is flexibly matched with, through the two π type match circuits, when external antenna end changes, it is ensured that channel radio
Believe that module itself remains optimal matching with antenna 206；Certainly, the die terminals match circuit 203 and antenna end matching electricity
Road 204 or other kinds of match circuit.
