摘要： Provided is an antenna apparatus which is capable of improving a gain in a specific direction, reducing an unnecessary gain in an angle range, and reducing its height. A radome 220 is formed such that a central portion positioned above a patch array antenna 130 is formed in different shapes in an outer wall and an inner wall. The central portion of the outer wall of the radome 220 is formed in a flat shape, and thus the height of the radome 120 is reduced. On the other hand, the center portion of the inner wall of the radome 220 is formed such that a radome thickness at a position of the radome 220 in directions in which an angle θ is about −45° and about +45° when viewed from the center of the patch array antenna 130 changes stepwise.

摘要： Provided is a built-in transmitting and receiving integrated radar antenna whose coverage of a horizontal radiation pattern is widened and whose space factor is improved by integrating high-frequency circuit component onto an antenna substrate while suppressing unnecessary waves. A first dielectric substrate (111) is formed into a three-layered structure in which a bias line (171) of an MIC is disposed between a second layer (111b) and a third layer (111c) and a second ground plane (114) is disposed between the first layer (111a) and the second layer (111b). Also, the second ground plane (114) is conductively connected with isolated through-holes (163, 164), so that a domain in which a feeding port (115) is disposed is isolated from a domain (B) in which the bias line (171) is disposed.
