Antenna structure and wireless communication device using same
An antenna structure with wide radiation bandwidth in a reduced physical space includes a housing, a first feed portion, and a second feed portion. The housing includes a metallic side frame, a metallic middle frame, and a metallic back board. The metallic side frame defines first and second gaps and the metallic back board defines a slot. The slot, and the first and second gaps, create a first radiation portion from the metallic side frame. The first and second feed portions are both electrically connected to the first radiation portion. When the first feed portion feeds current, the current flows through the first radiation portion, toward the second gap to excite a GPS mode and a WIFI 2.4 GHz mode. When the second feed portion feeds current, the current flows through the first radiation portion, toward the first gap to excite a WIFI 5 GHz mode.
