Abstract

Design and measurement of a planar antenna array realized in low temperature co-fired ceramic (LTCC) are presented. The antenna elements are ceramic-filled cavity resonators fed by an integrated laminated waveguide network and a slot in each resonator. The antenna is designed to operate in the 79-GHz frequency range. The array shows good impedance matching and a stable radiation pattern within a bandwidth of approximately 5 GHz. The presented results of a first design show that the antenna is a promising candidate for 79-GHz automotive or related applications and ideally suited for LTCC integration.
