Problems solved by technology

However, due to the lack of spectrum resources in the microwave frequency band, it cannot meet the requirements of higher-speed and larger-capacity transmission in the future. The millimeter-wave frequency band with rich spectrum resources has gradually attracted extensive attention from scholars at home and abroad.
However, communication in the millimeter-wave frequency band also faces many challenges. Its transmission distance is short and it is prone to multipath effects, so it cannot completely replace microwave technology.

Description

Technical field [0001] The present invention belongs to the field of antenna design technology, in particular to a microwave and millimeter wave large frequency ratio common aperture antenna structure combining MIMO technology. Background [0002] In recent years, 5G communication technology has developed rapidly, which has greatly improved the data transmission rate. Among them, the microwave band below 6GHz has been applied to 5G mobile communication systems in many countries such as China. However, due to the lack of spectrum resources in the microwave band and the inability to meet the requirements of higher speed and larger capacity transmission in the future, the millimeter wave band with rich spectrum resources has gradually attracted widespread attention from scholars at home and abroad. However, communication in the millimeter wave band also faces many challenges, its transmission distance is short and prone to multipath effects, so it cannot completely replace microwave...
