Summary:The present invention provides an antenna structure including an annular metal frame without a breakpoint, a first feed source and a second feed source. The annular metal frame is provided with a first radiating portion and a second radiating portion. The first feeding source feeds a current signal to the first radiating portion, so that the first radiating portion simultaneously excites a first mode and a second mode to generate signals of a first frequency band and a second frequency band. The second feeding source feeds a current signal to the second radiating portion, so that the second radiating portion simultaneously excites a third mode and a fourth mode to generate signals of a third frequency band and a fourth frequency band. The present invention also provides a wireless communication device having the antenna structure. The above antenna structure and the wireless communication device having the antenna structure can cover LTE-A low, medium and high frequency bands, a GPS frequency band and a WIFI
