Title:
BUILT-IN TRANSMITTING AND RECEIVING RADAR ANTENNA
Document Type and Number:
WIPO Patent Application WO/2011/125417
Kind Code:
A1
Abstract:
Provided is a built-in transmitting and receiving radar antenna wherein the coverage of a horizontal radiation pattern is enlarged and the space factor is improved by integrating high-frequency circuit components onto an antenna substrate while suppressing unnecessary waves. A first dielectric substrate (111) is formed as a three-layer structure in which a bias line (171) of an MIC is located between the second layer (111b) and the third layer (111c) and a second ground plane (114) is located between the first layer (111a) and the second layer (111b). Also, the second ground plane (114) is conductively connected to isolated through holes (163, 164), so that an area in which a feeding port (115) is located is isolated from an area (B) in which the bias line (171) is located.
