Abstract

This paper presents the integration and experimental validation of a multi-feed holographic-based leaky wave antenna (HLWA) array into an automotive MIMO radar system. First, a novel multi-layer integration concept with a quasi-coaxial transition is designed and fabricated, enabling rotationally symmetric surface wave excitation. Measured S-parameters from 76 GHz to 81 GHz show reflection coefficients below −10 dB and inter-port coupling
