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 () is formed into a three-layered structure in which a bias line () of an MIC is disposed between a second layer () and a third layer () and a second ground plane () is disposed between the first layer () and the second layer (). Also, the second ground plane () is conductively connected with isolated through-holes (), so that a domain in which a feeding port () is disposed is isolated from a domain (B) in which the bias line () is disposed.
