Abstract

The invention discloses a high-isolation double-unit MIMO antenna which is characterized in that the antenna comprises a dielectric substrate (104), two antenna radiation units (101), two microstrip feed lines (102), a T-shaped stub (104), two H-shaped resonators (105) and a grounding board (106); the two radiation units are planar E-shaped metal patches; and the opening directions of the two radiation units are obliquely outward. The working frequencies of the MIMO antenna are 1575MHz and 2650MHz. The MIMO antenna can be used for GPS and LTE-A communication and furthermore has an obvious decoupling effect. The MIMO antenna has advantages of simple design, compact structure, high convenience in manufacture, and low cost.

Description

technical field [0001] The present invention relates to a high-isolation dual-element MIMO antenna according to claim 1, which can be used in the fields of GPS and LTE-A communication. Background technique [0002] In the field of modern communication, when we design antennas, the main challenge is to increase the frequency band of the antenna and increase the isolation between the antennas so that the antenna can be used in different application fields, such as GPS and LTE-A. [0003] The Global Positioning System (GPS) is widely used in mobile phones, airplanes, automobiles, etc. Generally civilian GPS receives L1 and L2 frequency band signals. The frequency of the L1 frequency band is 1575.42±10MHz, and the frequency of the L2 frequency band is 1227.60±10MHz. [0004] LTE-A is an evolved version of LTE technology, which uses a series of advanced technologies, including carrier aggregation, uplink / downlink multi-antenna enhancement, multi-point coordinated transmission, ...
