Embodiment Construction

[0028] This embodiment aims to provide a multiple-input multiple-output antenna capable of increasing isolation, and the isolation of the antenna is increased by using an electromagnetic bandgap structure. The electromagnetic bandgap structure is a periodic structure developed from the photonic bandgap structure. The electromagnetic bandgap structure can control the propagation of electromagnetic waves to a certain extent, specifically showing that it prevents the propagation of electromagnetic waves in certain frequency bands, and has certain band gap characteristics. In essence, the electromagnetic bandgap structure is a bandstop filter composed of different dielectrics, metals or their mixture units arranged in a periodic manner. Due to the existence of this characteristic, the electromagnetic bandgap structure can be applied to the microstrip antenna, which is set between the antenna units as a high-impedance circuit to suppress the surface waves of the substrate, suppress...

Abstract

The invention discloses a multi-input multi-output antenna and a mobile terminal, comprising: an antenna substrate, a plurality of antenna units, an electromagnetic bandgap structure and a floor, the antenna units are attached to the surface of the antenna substrate at intervals, the The antenna substrate is overlapped with the floor, the electromagnetic bandgap structure is arranged at a position between two antenna units of the antenna substrate, and the electromagnetic bandgap structure is connected to the floor. To sum up, the present invention can improve the isolation of the MIMO antenna by setting the electromagnetic bandgap structure, so as to increase the radiation efficiency of each antenna unit and improve the communication data transmission rate.

Description

technical field [0001] The invention relates to mobile terminal communication technology, in particular to a multiple-input multiple-output (MIMO) antenna and a mobile terminal. Background technique [0002] With the rapid development of mobile wireless communication technology, the requirements for large-capacity information transmission are getting higher and higher. How to deal with the ever-increasing number of mobile users, without adding additional frequency band bandwidth, and under the condition of scarce spectrum resources, how to transmit data with high reliability, high speed and high coverage has become a problem in today's wireless communication field An important and urgent research topic. It is against this background that MIMO emerges as the times require. MIMO can increase the capacity and spectrum utilization of wireless communication systems by tens or even hundreds of times, and can effectively combat multipath fading. One of the techniques. But at the...
