Abstract

A 77-GHz four-beam plano-convex lens antenna with SIW slot feed for automotive radar is presented. The primary feed consists of four substrate integrated waveguide (SIW) slots which are designed with complete routing and SIW to grounded co-planar waveguide (GCPW) transition. The transition is designed for the integration with a 3D embedded wafer level ball grid array (eWLB) module as well as for onwafer probing measurements, respectively. The antenna prototype at 77 GHz achieves the gain of 24 dBi and a combined beam coverage of ±12°. The simulated and measured results agree quite well.
