Technical field
The invention belongs to radio signal transmission field more particularly to a kind of antennas.
Background technology
The multi mode terminal that 2G, 3G and the 4G of present mobile phone from 2G simple in the past till now are shared, thus will
The frequency band for seeking debugging antenna is wider, and the debugging area and space that antenna needs can biggers.However the trend of mobile phone is to get over now
It does thinner, and requires metal edge frame, these are all unfavorable for the radiation of antenna, and are limited by interior of mobile phone space, and antenna is very
Difficulty accomplishes than preferably index, take into account mostly there are high frequency (frequency band of more than 1.6G) and low frequency (frequency band of below 1G) difficulty or
It is difficult to meet the needs of some frequency bands simultaneously.
Two ways is generally used now for the antenna of multi mode terminal：(1) high and low frequency uses same antenna sheet
Body, high and low frequency have public signal transmssion line (i.e. using common signal access point), so only need an antenna sky
Between；(2) high and low frequency uses separated two antenna bodies, and high and low frequency signal does not use common signal line, so
Need two day space of lines.Space needed for the antenna of mode (1) is few, but antenna adjustment is difficult to take into account high and low frequency simultaneously.
Mode (2) has used two day space of lines to separate high and low frequency, can so take into account high and low frequency simultaneously, but in hand

The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figures 1 and 2, antenna 100 provided in an embodiment of the present invention can emit used in one and receive aerogram
Number electronic equipment 200 (such as mobile phone) in.The antenna 100 includes an antenna body 10 and a switch modulation demodulator
(switch modem) 20 (see Fig. 3).In the present embodiment, which is tablet inverted F (Planar Inverted
F Antenna, PIFA) antenna body.The electronic equipment 200 includes a printed circuit board (PCB) (printed circuit
Board, PCB) 210 and a ground plane 220.
The ground plane 220 is arranged on the PCB210.The PIFA antenna bodies 10 are arranged on the ground plane 220, and with
The ground plane 220 is spaced apart, forms an air layer.Test lead 211 there are one being set on the PCB210 (see Fig. 3).
The PIFA antenna bodies 10 are rectangle, and with the first long side 11, the second long side 12, the first short side 13 and second
Short side 14.First long side 11 is oppositely arranged and is mutually parallel with second long side 12, first short side 13 and second short side
14 equal vertical connections, first long side 11 and second long side 12.On the PIFA antenna bodies 10 set there are one short circuit point 15,
One low frequency signal access point 16 and a high-frequency signal access point 17.
With reference to shown in Fig. 3, the switch modulation demodulator 20 be connected electrically in the printed circuit board (PCB) 210 and the antenna body 10 it
Between, and including first input end 21, the second input terminal 22 and output terminal 23.The switch modulation demodulator 20 can as needed by
The first input end 21 is electrically connected with the output terminal 23 or is electrically connected second input terminal 22 with the output terminal 23.
The short circuit point 15 is located at the near intersections of first long side 11 and first short side 13, and extends on the short circuit point 15
Go out a conducting wire to be electrically connected the PIFA antenna bodies 10 with the ground plane 220.
The low frequency signal access point 16 is located between the short circuit point 15 and second long side 12, and is set close to the short circuit point 15
It puts.The line of the low frequency signal access point 16 and the short circuit point 15 is mutually parallel with first short side 13.The low frequency signal accesses
Point 16 extends one bar of conducting wire (i.e. low frequency signal end 101) by the of the PIFA antenna bodies 10 and the switch modulation demodulator 20
One input terminal 21 is electrically connected.
