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 first dielectric substrate, a first metal sheet and a second metal sheet. The first and second metal sheets are attached to the two opposite surfaces of the first dielectric substrate. A first feeder line is arranged in a way of enclosing the first metal sheet. A second feeder line is arranged in a way of enclosing the second metal sheet. The first and second feeder lines feed signals in the first and second metal sheets in a coupling way respectively. A first micro-channel structure is hollowed in the first metal sheet to form first metal wiring on the first metal sheet. A second micro-channel structure is hollowed in the second metal sheet to form second metal wiring on the second metal sheet. The first and second feeder lines are electrically connected. A second dielectric substrate also covers the first metal sheet. According to the antenna, the metal sheets are arranged on the two surfaces of the first dielectric substrate, so that the area of the antenna is fully utilized, the antenna can work at low working frequency in such an environment, and the requirements of miniaturization, low working frequency and broadband multimode for the antenna are met. In addition, the invention also relates to a multiple input multiple output (MIMO) antenna with a plurality of antennae.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an antenna and a MIMO antenna with 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 the w...
