Abstract

LTCC has proven to be an excellent technology for high density integration of passive multilayer circuits; frequency of operation has been continuously increased and now is reaching the higher mm-wave range, for example for automotive radar sensor applications. This contribution presents design approaches for planar antennas in the 76 GHz to 81 GHz frequency range - a slotted synthetic waveguide antenna and a grid antenna array. Four chains of a grid antenna then are integrated on a single LTTC substrate with a SiGe four-channel radar MMIC to form a short-range automotive sensor (with a range of a few tens of meters).
