Embodiment Construction

[0028] This embodiment aims to provide a multiple-input multiple-output antenna that can increase isolation, and increase the isolation of the antenna by adopting an electromagnetic band gap structure. The electromagnetic band gap structure is a periodic structure developed from the photonic band gap structure. The electromagnetic band gap structure can control the propagation of electromagnetic waves to a certain extent, which is specifically manifested in preventing the propagation of electromagnetic waves in certain frequency bands, and has certain band gap characteristics. Essentially, the electromagnetic bandgap structure is a band-stop filter composed of different media, metals or their hybrid units arranged in a periodic manner. Because of this feature, the electromagnetic band gap structure can be applied to microstrip antennas, which are arranged between the antenna units as a high-impedance circuit to suppress the surface waves of the substrate, suppress the high-orde...

Abstract

The invention discloses a multiple-input multiple-output antenna and a mobile terminal. The multiple-input multiple-output antenna comprises an antenna substrate, a plurality of antenna units, an electromagnetic bandgap structure and a floor, wherein the antenna units are pasted on the surface of the antenna substrate at intervals; the antenna substrate is overlapped with the floor; the electromagnetic bandgap structure is arranged at a position between two of the antenna units on the antenna substrate and is connected to the floor. According to the multiple-input multiple-output antenna, due to the arrangement of the electromagnetic bandgap structure, the isolation of the MIMO (multiple-input multiple-output) antenna can be enhanced, so that the radiation efficiency of each antenna unit can be improved, and the communication data transmission rate is increased.

Description

Technical field [0001] The present 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 growing number of mobile users, without increasing additional frequency band bandwidth, and under the condition of scarce spectrum resources, transmitting data with high reliability, high speed and high coverage has become the field of wireless communication today An important and urgent research topic. It is in this context that MIMO came into being. MIMO can increase the capacity and spectrum utilization of wireless communication systems by tens or even a hundred times, and can effectively combat multipath fading. It has become the key to today’s new generation of mobile communicatio...
