Antennas and Wireless Communication Devices

Abstract

The invention discloses an antenna, which comprises a dielectric substrate, grounding units attached to the dielectric substrate and a metal structure attached to the dielectric substrate, wherein the metal structure comprises an electromagnetic response unit, a metal opening ring wrapping the electromagnetic response unit and a feed point connected with the extension tail end of one end of the metal opening ring; the electromagnetic response unit comprises an electric-field-coupled structure and at least one metal sub structure; and the metal sub structures are arranged in the electric-field-coupled structure. Due to the design, the physical length of the antenna is increased; a radio frequency antenna working at extremely low working frequency can be designed in extremely small space, and the physical limitation that the conventional antenna is limited by the space area when working at low frequency is prevented; and the requirements on minimization, low working frequency and broadband multimode of a mobile phone antenna are met. Furthermore, a design mode with relatively low cost is supplied to the design of the antenna of wireless communication equipment.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna and a wireless communication device using the antenna. Background technique [0002] With the high development of semiconductor technology, higher and higher requirements are put forward for the integration of today's electronic systems, and the miniaturization of devices has become a technical issue of great concern to the entire industry. However, unlike the development of IC chips following "Moore's Law", radio frequency modules, another important component of electronic systems, face the difficult technical challenge of device miniaturization. The radio frequency module mainly includes main components such as frequency mixing, power amplifier, filter, radio frequency signal transmission, matching network and antenna. Among them, the antenna is the radiating unit and receiving device of the final radio frequency signal, and its working characteristics will directly affect t...

Problems solved by technology

However, the impedance matching network additionally increases the feeder design of the electronic system and increases the area of ​​the radio frequency system. At the same time, the matching network also introduces a lot of energy loss, which is difficult to meet the system design requirements of low power consumption.
