The present invention provides an antenna device and mobile communication equipment, including a first resonant antenna and a second resonant antenna. The first resonant antenna includes a metal shell and a metal sheet, wherein the metal shell includes an integrally formed metal backplane and a metal frame, and the metal frame surrounds the metal backplane; the metal sheet and the metal shell form a non-closed cavity, and the metal There is at least one gap and at least one opening between the outer periphery of the sheet and the metal frame. The second resonant antenna is located at the opening and includes a radiation unit and a coupling unit. The antenna device and the mobile communication device of the present invention respectively work in the GPS signal frequency band and the WIFI signal frequency band through the first resonant antenna and the second resonant antenna, thereby realizing GPS and WIFI communication in the case of a full metal casing.
Description
technical field [0001] The invention relates to the field of antennas, in particular to antenna devices and mobile communication equipment. Background technique [0002] In the current wireless communication equipment, all-metal shells are increasingly used due to their advantages such as beautiful appearance, high structural strength, and excellent thermal conductivity. Wireless communication equipment generally transmits electromagnetic signals through an antenna device, but the antenna device is easily shielded and interfered by a metal casing when receiving and sending signals. [0003] In order to overcome signal shielding and interference, the housing of a wireless communication device in the prior art is usually composed of two parts, that is, a metal part and a non-metal space. The antenna radiation unit is designed in the non-metal space of the casing, so that the radiation of the antenna is not shielded by the metal part or the influence of the metal casing is min...
