The utility model is with low frequency radiation portion and two kinds of difform metal micro-strip pasters of high-frequency radiation part, be pasted on vinyon and place on the metal ground plate of mobile phone, the low frequency radiation portion of antenna is in parallel mutually through the transport part with high-frequency radiation part, reactance with the short circuit metal dististyle compensates mutually again, on two frequencies resonance taking place, makes the work of antenna two-band.Passing through coaxial cable feed---coaxial outer conductor connects the mode of ground connection flat board, inner wire connection antenna I/O end, finishes the test job of antenna.
The advantage of the utility model embedded in mobile phone formula antenna is:
1. antenna for mobile phone of the present utility model in the concave structure that high-frequency radiation part is stretched into the formation of low frequency radiation portion, is adjusted the relative position between the high and low frequency Department of Radiation, makes antenna for mobile phone have splendid signal receiving performance;
2. the acceptance division of the low frequency radiation portion of the utility model antenna for mobile phone and base portion form a concave structure, and acceptance division one end of high-frequency radiation part stretches in this concave structure, has dwindled the mobile phone space that takies, and make antenna for mobile phone have the small and exquisite advantage of volume.
