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.

Abstract

The invention relates to an antenna, which comprises a medium substrate and a grounding unit which is adhered onto the medium substrate, and the antenna also comprises a metal structure which is adhered onto the medium substrate, the metal structure comprises an electromagnetic response unit, a metal open ring which is arranged surrounding the electromagnetic response unit and a feed point which is connected with the metal open ring, and the electromagnetic response unit comprises an electric field coupling structure. Such design is equivalent to the increase of a physical length of the antenna, a radio frequency antenna which works under an ultra-low working frequency can be designed inside a ultra-small space, so that the physical limitation that the traditional antenna is controlled by the space area when working under the low frequency can be solved, and the miniaturization, low working frequency and broadband multimode requirements of a mobile phone antenna can be met. Simultaneously a design way with lower cost can be provided for the antenna design of a wireless communication device.

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...
