Description
Technical Field
The invention relates to the technical field of patch antennas, in particular to a millimeter wave wide-bandwidth beam patch antenna.
Background
The rich communication bandwidth of the millimeter wave frequency band provides an effective way for high-speed communication transmission. Therefore, the millimeter wave antenna has wide application prospects in the fields of satellite communication, automatic driving, factory automation, fifth-generation mobile communication and the like. Typically, such application scenarios require higher data transmission rates, and thus the millimeter wave antenna needs to operate in a broadband to meet the bandwidth requirements of the high data transmission rates. In addition, the path loss of the millimeter wave frequency band is severe, and the scanning phased array antenna technology is required to be used for beam forming to improve the gain, so that the high path loss is compensated, and the transmission distance of the system is increased. However, the phased array antenna faces a problem of gain drop during wide-angle scanning, and in order to reduce the gain drop during wide-angle scanning of the phased array antenna, it is necessary to design a millimeter wave antenna having a wide beam width. In summary, millimeter wave systems are in urgent need of wide bandwidth beam millimeter wave antennas.
In recent years, studies on how to widen the beam width of an antenna element have been increasing at home and abroad. By loading the omnidirectional monopole to the patch antenna and introducing the current in the vertical direction, the beam width of the patch antenna can be effectively improved, but the height of the antenna section is obviously increased or the plane size is larger. The beam bandwidth of the antenna can also be improved by reducing the effective aperture of the patch antenna, for example, reducing the distance between two radiating slots or transforming the patch antenna into a single magnetic current slot radiation, but the antenna gain is seriously reduced, and the working bandwidth of the design is narrow at present. A wide beam radiation pattern can be obtained by combining the radiation of magnetic dipoles and electric dipoles, but the cross polarization of such a design is large; wide beam radiation can also be achieved by loading the patch antenna with parasitic elements, but such designs are typically narrower in bandwidth or larger in size.
The wide-beam patch antenna in the prior art has one or more of the problems of high profile, large size, narrow bandwidth, poor stability of beam width in bandwidth, large cross polarization, unsuitability for millimeter wave application and the like.
