Abstract

The invention discloses a microwave and millimeter wave large-frequency-ratio common-caliber antenna combined with an MIMO technology. On a microwave and millimeter wave large-frequency-ratio common-caliber antenna, four substrate integrated waveguide back cavity patch antennas and four electric dipoles of an electromagnetic dipole are shared through structural design, a 2 * 2 MIMO antenna array is formed to radiate millimeter wave signals, a dual-polarized electromagnetic dipole antenna is used in a microwave frequency band, the MIMO technology is combined in a millimeter wave frequency band, and the antenna has a wide application prospect. Finally, the large-frequency-ratio common-aperture antenna which has the characteristics of high integration level, high isolation and the like, is combined with the MIMO technology in a millimeter wave frequency band and can cover multiple frequency bands is realized.

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...

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.
