Abstract
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.
