Abstract

The invention discloses a compact dual-band antenna of large frequency ratio covering sub-6G and 60GHz. The compact dual-band antenna comprises a dielectric substrate, a broadband monopole, a compact microstrip resonant unit, a millimeter wave decoupling patch array, a rectangular metal floor and a lumped port. The broadband monopole is printed on the upper surface of the dielectric substrate, consisting of a circular microstrip line and a microstrip feed line. The compact microstrip resonant unit is connected to the millimeter wave decoupling patch array and the microstrip feed line. The millimeter wave decoupling patch array comprises millimeter wave patches, rectangular slottings and decoupled microstrip lines. The rectangular slottings are located on the millimeter wave patches, and the decoupled microstrip lines are located between the millimeter wave patches. The rectangular metal floor is printed on the lower surface of the dielectric substrate. The lumped port is connected to the millimeter wave decoupling patch array and the rectangular metal floor for feeding. The compact dual-band antenna of the invention has wide frequency band and high gain effect, and can meet the application requirements of the 5G low frequency band and the 60GHz millimeter wave band.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a compact dual-frequency antenna with large frequency ratio covering sub-6G and 60GHz. Background technique [0002] Since the dual-frequency antenna meets the requirements of multiple operating frequency bands, the overall size of the antenna can be effectively saved, thereby realizing the miniaturization of the entire antenna system. With the development of mobile communication technology, 5G communication is gradually entering into use. 3GPP has designated the microwave frequency band below 6GHz (sub-6G for short) as the 5G low frequency band, and the 24.25-52.6GHz millimeter wave frequency band as the 5G high frequency band. At the same time, in order to take into account the needs of future millimeter-wave communications, dual-band antennas with large frequency ratios have become one of the hot research topics. [0003] According to investigation and underst...
