Solving the printed words such as " first ", " second " is not to be defined quantity and execution order.
This utility model embodiment provides a kind of antenna, and with reference to shown in Fig. 1, this antenna includes:
First annular coil 11 and the second loop coil 12.
Concrete, first annular coil 11 and the second loop coil 12 can by metal with
And other conductive materials make and are formed.Its processing technology can be: at flexible circuit board (English
Literary fame claims: Flexible Printed Circuit, is called for short: by patterning processes system on PCB)
Formed, it is also possible to for by directly conductor wire being carried out coiling making formation, it is also possible to by having
The metal edge frame having the communication equipment of this antenna is formed.Additionally, in this utility model embodiment
The ring that loop coil is formed can be that circle can also be for other shapes.This utility model embodiment
In to first annular coil 11 and the concrete form of the second loop coil 12, processing technology with
And shape is all not construed as limiting.
Wherein, the head end 111 of first annular coil 11 and the input pin 101 processing chip 100
Connecting, the end 112 of first annular coil 11 and the output pin 102 processing chip 100 connect
Connect.The head end 121 of the second loop coil 12 is connected with the input pin 101 processing chip 100,

The most first annular coil 11 and the second annular 12 are connected to process chip in parallel
Between input pin 101 and the output pin processing chip of 100, so first annular coil
11 and second loop coil respectively with process the input pin of chip and output pin constitutes loop,
Can independently be operated.
Also, it should be noted in the course of the description in order to distinguish ring in this utility model embodiment
The two ends of shape coil, wherein will be defined as toroidal head end in one end, and the other end is defined as ring
The end of shape coil, and the application limits loop coil two ends not by head end and end and exists
The function realized in practical work process, such as: in loop coil, sense of current can be
Toroidal end is flowed to, it is also possible to for there being toroidal end by toroidal head end
Flow to toroidal head end.Additionally, in any case, those skilled in the art can also
Toroidal head end and end are interchangeable.Equally, this utility model embodiment is describing
During in order to distinguish process chip two pins, be input pipe by one of them pin definitions
Foot, another pin definitions is output pin, and the application is not by input pin and input pipe
Foot limits process chip flow direction of electric current in practical work process.
The direction, axis 113 place of first annular coil 11 is first direction, the second loop coil
