1 Introduction

This application note guides the reader through the process of designing an antenna for mmWave radar sensor boards. Since PCB-printed patch antennas are one of the most common antenna types used for mmWave radar applications, this document focuses exclusively on that technology. Antenna-on-Package (AoP) and Launch-on-Package (LOP) designs are outside the scope of this application note.
