The invention discloses an electronic device and an antenna unit thereof. The antenna unit includes a feeding terminal, a ground terminal, a matching circuit, a first conductive portion, a second conductive portion, a first extensive arm, a second extensive arm and a third extensive arm. The matching circuit is electrically connected to the feeding terminal and the ground terminal respectively. The second conductive portion includes a first edge and a second edge on opposite sides. The first extensive arm is disposed to extend from a first corner of the second conductive portion to the first conductive portion. The second extensive arm is disposed to extend outward from a second corner of the second conductive portion. The third extensive arm is disposed to extend outward from a third corner of the second conductive portion. The antenna unit forms multiple resonant modes.
Description
technical field [0001] The invention relates to an antenna unit, in particular to an antenna unit used for an electronic device with a metal casing. Background technique [0002] Today's electronic devices, such as notebook computers, tablet computers and other products, often use metal casings for aesthetic reasons. However, due to the limitation of the metal casing, the electronic device with a full metal casing makes it difficult to perform well in the efficiency and radiation pattern of the internal antenna, resulting in affected signal transmission quality. [0003] In addition, for the portability of the electronic device, the space inside the electronic device needs to be properly utilized. The space for installing an antenna on a small or portable electronic device is very limited. Designing an antenna capable of simultaneously transmitting and receiving multiple wireless frequency bands in a space with good antenna efficiency is an important research and developmen...
