ANTENNA AND WIRELESS COMMUNICATION DEVICE

摘要

An antenna comprising a dielectric substrate and a ground unit attached to the dielectric substrate. The antenna also comprises a metal structure attached to the dielectric substrate. The metal structure comprises an electromagnetic response unit, a metal snap ring arranged around the electromagnetic response unit, and a feedpoint connected to one end of the metal snap ring. The electromagnetic response unit comprises an electric field coupling structure. This design is equivalent to extending the physical length of the antenna, thus allowing the designing of radio-frequency antenna operating at extremely low operating frequency within an extremely compact space, solving the physical limitation in conventional antennae when working at low frequencies of the antenna being restricted by space and area, meeting the requirements of miniaturization, low operating frequency, and broadband multimode of mobile phone antennae. At the same time, a design scheme of reduced costs is also provided for designing antenna of wireless communication devices.
