Abstract

The invention discloses a novel high-gain, wide-angle scanning lens antenna based on a stepped medium, belonging to the technical field of microwave and millimeter wave antennas. The antenna includesa lens antenna and a patch antenna feed array horizontally positioned below the lens antenna. The lens antenna includes an upper spherical shell portion, a lower circular table portion, and an inner sector spherical portion which are fitted tightly. The different thickness and dielectric constant of each part of the lens antenna can effectively collect electromagnetic wave, readjust the amplitudeand phase of electromagnetic wave, and achieve high gain. The contour of the lower circular table can refract electromagnetic wave effectively. Based on the placement position of the feed array of thepatch antenna, the large-angle scanning can be realized effectively. The invention can be used in millimeter wave communication system and radar communication, and has the advantages of ensuring highgain and scanning in a large range at the same time, simple power feeding, small number of feed sources, convenient installation and low cost.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave antennas, and relates to a novel high-gain, wide-angle scanning lens antenna with gradient medium gradient. Background technique [0002] In recent years, the millimeter wave communication system has attracted much attention due to its high data capacity. It is widely used in point-to-point, point-to-multiple communications, WIFI systems, radar systems and other fields. Therefore, the design of large-angle scanning antennas is very necessary. However, due to the large path loss in the millimeter wave frequency band, this requires the antenna to have high gain characteristics at the same time. However, traditional high-gain, multi-angle scanning lenses, such as phased arrays, are costly to implement, and it is difficult to accurately control large-scale transceiver components. Therefore, designing a millimeter-wave high-gain, wide-angle scanning lens antenna is still a challen...
