Title: Antenna device and transmission/reception wave module
Inventor: YAMADA HIDEAKI
IPC: H01Q3/14
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To provide an antenna device capable of suppressing the change of the gain at the beam scanning due to the displacement of a primary radiator against a dielectric lens and executing a search with a uniform gain over a wide angle range. SOLUTION: In a primary radiator, a position dislocated from the optical axis of a dielectric lens 2 is set to be the focal plane of the dielectric lens 2. The primary radiator is made away from the focal plane when the primary radiator comes on the optical axis. Thus, a gain change due to the change of aperture efficiency and aberration due to dislocation from the optical axis like the 1a and 1c (shown be Figure) is suppressed. Thus, the fluctuation of the aperture efficiency and the aberration of the dielectric lens 2 due to the displacement of the primary radiator can be controlled differently from the case of displacing only the focal plane of the primary radiator.
