Description
Abstract: This communication presents the design and experimental verification of a
substrate integrated waveguide fed lens antenna for 79 GHz automotive radar applications.
The proposed integrated lens antenna consists of a six layer cylindrical Luneburg lens
illuminated by 17 source elements of substrate integrated waveguide fed by a planar log
periodic dipole antenna array. The Luneburg lens is developed by using a unique foam
material AirexR82 ($\varepsilon _ {r}= 1.12$), which is drilled and pressed to achieve the …
