Abstract
An embedded antenna used in mobile phone includes a lower and a higher frequency portions connecting with the lower frequency portion via a first connecting portion. The lower frequency portion is a bended structure in planar inverted F antenna (PIFA) shape. The higher frequency portion is a loop antenna working in two different higher frequencies, including a first higher frequency portion and a second higher frequency portion connecting with the first one via a second connecting portion. The first connecting portion defines a feeding portion and a grounding portion. The second higher frequency portion defines another grounding portion. An electric current is formed between the first and the second higher frequency portions and can heighten the gain and the frequency band of the antenna. Additionally, a loudspeaker is disposed in a receiving space formed between the lower and higher frequency portions to save space with lowest influence to the antenna.
