Portable communication terminal and PIFA antenna thereof

The utility model relates to a portable communication terminal and PIFA antenna thereof. The PIFA antenna includes base plate, the first metal layer, second metal level, radiation fin and parasitic element, sets up slottedly on the radiation fin. The radiation fin has a natural resonance point, and the groove can be with the electric current redistribution on the radiation fin to change electric current length. Consequently, impedance match can be realized at high frequency point more to the radiation fin to introduce a new intermediate frequency resonance point. Further, the radiation fin iswhen radiating, thus still can be coupled to parasitic element with the electromagnetic wave goes up excitation parasitic element. Parasitic element by after the excitation can produce more high -frequency resonance to introduce a new high -frequency resonance point again. Because groove and parasitic element introduce intermediate frequency and high -frequency resonance point respectively on thebasis of radiation fin nat
