アンテナシステム

Japanese Patent JP7193805

B2

To provide a technique for changing the propagation direction of a narrow beam which is a radio wave whose propagation direction is controlled in a specific direction in wireless communication while maintaining the state of the narrow beam.SOLUTION: An antenna system includes a radio wave source that radiates radio waves, a rear reflector that reflects the radio wave of the radio wave source located in a plane in which the irradiation direction in which the radio wave source radiates radio waves is a normal direction, and which includes the radio wave source, and a plurality of flat plate-shaped dielectric plates located on the radial side with respect to the rear reflector and parallel to the back reflector, and when a distance between the back reflector and the dielectric plate in the radial direction is defined as a first type distance, and a distance between the two adjacent dielectric plates in the radial direction is defined as a second type distance, and at least one of the plurality of first type distances is different from the other first type distance, and at least one of the plurality of second type distances is different from the at least one first type distance.SELECTED DRAWING: Figure 1
