Abstract :
A printed antenna composed of via-wall-cavity with a rim excited by a bow-tie antenna is presented that suppresses surface-waves generated in thick substrate, consequently exhibits wideband antenna characteristics. It is demonstrated that a developed 2 times 4-element array for UWB automotive radar performs 15 dBi gain over 20% bandwidth, and has a band rejection notch which reduces effectively interferences between UWB radars and radio services using the restricted frequency band.
