Problems solved by technology

However, due to the very short wavelength of the signal in the millimeter wave frequency band, it poses great challenges to the processing, interconnection, and massive MIMO array application of the antenna
Although planar printed antennas such as microstrip patch antennas are easy to process, they tend to have narrow bandwidths and low radiation efficiency in the millimeter wave band
Although the horn antenna has superior performance in the millimeter-wave frequency band, the traditional high-frequency horn antenna is difficult to process, high in cost, large in size, complex in feeding structure, and difficult to integrate with planar circuits or perform compact array applications.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband millimeter-wave antenna. The antenna works in the millimeter-wave frequency band and has the characteristics of low complexity and easy integration with planar circuits. Background technique [0002] Antennas are one of the key components of wireless communication systems. The development needs of future mobile communication with high capacity and high transmission rate require more spectrum resources to support. Millimeter-wave frequency band mobile communication is the mainstream development trend of future mobile communication. There are abundant spectrum resources in the millimeter-wave frequency band, which can meet the development needs of future mobile communication. However, since the signal wavelength is very short in the millimeter-wave frequency band, it poses great challenges to antenna processing, interconnection, and massive MIMO array applications. A...
