Title: FOUR-ELEMENT MIMO ANTENNA WITH DIFFERENT POLARIZATIONS AND DIRECTIONAL PATTERNS
Abstract:
Disclosed is a four-element MIMO antenna with different polarizations and directional patterns, the MIMO antenna comprising a dielectric substrate, a base plate printed on a back face of the dielectric substrate, and a MIMO antenna and an isolation strip both printed on a front face of the dielectric substrate. The MIMO antenna is formed of four identical antenna elements arranged through rotation around the centre by 90 degrees. The isolation strip is vertically arranged above the dielectric substrate, and the centre of the isolation strip coincides with the centre of the MIMO antenna. In the present invention, the MIMO antenna is formed of four identical antenna elements arranged through rotation around the centre by 90 degrees, and a method of loading a patch short-circuit metal post is used, such that the area of the antenna is reduced by half with respect to that of a traditional half-wavelength patch antenna, and the structure thereof is compact; a microstrip printing technology is used, such that the antenna has a higher integration degree, is lighter in weight, lower in costs and has a shorter processing cycle; and by using the vertical isolation strip, the correlation coefficient between antenna ports is reduced, and compared with other decoupling techniques, the structure is more compact on the premise of ensuring that same has a high isolating effect.
