Abstract
Official abstract text for this publication.
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 ( 111 b ) and a third layer ( 111 c ) and a second ground plane ( 114 ) is disposed between the first layer ( 111 a ) and the second layer ( 111 b ). 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A built-in transmitting and receiving integrated radar antenna, comprising: a transmitting antenna disposed at one end side of one surface of a first dielectric substrate; a receiving antenna disposed at another end side of one surface of the first dielectric substrate; an EBG (Electromagnetic Band Gap) disposed between the transmitting and receiving antennas; partition through-holes respectively disposed between the transmitting antenna and the EB…
