DUAL-FREQUENCY ANTENNA, MIMO ANTENNA DEVICE AND 2.4GHZ/5.8GHZ DUAL-FREQUENCY WIRELESS COMMUNICATION DEVICE

摘要

Disclosed are a dual-frequency antenna, a MIMO antenna device and a 2.4GHz/5.8GHz dual-frequency wireless communication device. The dual-frequency antenna includes a feeder point, a feeder connected to the feeder point and a metal structure, wherein the feeder and the metal structure are coupled to each other, and the dual-frequency antenna makes electromagnetic waves in at least two different bands resonate. The present invention employs manual electromagnetic material technology to design a relevant electromagnetic wave resonance response metal structure library, wherein the size of these structures is much smaller compared with traditional antenna structures, enabling the physical size of the antenna to be free from the restriction of the physical length of a half wavelength and enabling the structures to be embedded in various wireless electronic devices conveniently; a metal structure with matched resistance is selected according to the application product and then sorted, tested and adjusted continuously to finally optimize a metal structure suitable for a dual-frequency antenna, enabling the selected metal structure to make electromagnetic waves in at least two different bands resonate, meeting the operating requirements of wireless electronic devices such as miniaturization, an embedded antenna and multi-mode.
