Antenna device and wireless communication equipment

The invention relates to an antenna device. The device comprises a metal floor which is provided with a clearance area; a feed port connected with the metal floor; a first radiator arranged in the clearance area and connected with the metal floor; a radiation branch knot, wherein one end of the radiation branch knot is connected with the feed port, and the other end is connected with the first radiator; and a second radiator arranged in the clearance area, wherein the second radiator is connected with the metal floor and forms electromagnetic coupling with the first radiator. According to the antenna device, resonance of multiple frequency bands can be realized on a single antenna at the same time, and the occupied space is small. The invention also relates to wireless communication equipment. 本申请涉及一种天线装置，包括金属地板，设置有净空区；馈电端口，与金属地板连接；第一辐射体，设于净空区且与金属地板连接；辐射枝节，一端与馈电端口连接，另一端与第一辐射体连接；以及第二辐射体，设于净空区，第二辐射体与金属地板连接且与第一辐射体形成电磁耦合。上述天线装置能够在单一天线上同时实现多个频段的谐振，且占用空间小。本申请还涉及一种无线通讯设备。
