A multi-frequency antenna comprises a circuit board which is provided with an insulating dielectric layer, and a first ground plane, an impedance matching circuit and a second ground plane which are formed on the circuit board. Part of the insulating dielectric layer is exposed out of the first ground plane. A slot antenna radiation body, consisting of a first radiation body and a second radiation body, is formed in the exposed part of the insulating dielectric layer. The first radiation body includes a first impedance matching part and a first resonant part, which are respectively on two opposite sides of a projection block of the impedance matching circuit. The second radiation body is of the same structure as the first radiation body. The first resonant part includes multiple first bends. A first continuous bend group of the first bends forms a first block, and the first block is provided with a first pattern. A second continuous bend group of the first bends forms a second block, and the second block is provided with a second pattern. The first pattern is different from the second pattern. The first continuous bend group and the second continuous bend group each include at least five consecutive first bends. The second resonant part of the second radiation part is the same with the first resonant part.
Description
technical field [0001] The invention relates to a multi-frequency antenna. Background technique [0002] The technology of wireless communication devices has grown day by day in recent years. In a wireless communication device, an antenna can transmit and / or receive wireless signals. Therefore, in the wireless communication device, the performance of the antenna has great influence. [0003] In order to improve the performance of wireless communication devices, antenna technology is also gradually developed. How to make the antenna miniaturized without affecting the performance of the antenna is the direction of the industry's efforts. Contents of the invention [0004] The object of the present invention is to provide a multi-frequency antenna, which can achieve area reduction and high antenna performance. [0005] In order to achieve the above object, according to an embodiment of the present invention, a multi-frequency antenna is proposed including a circuit board ...
