Millimeter wave phased array antenna and front end co-design for smartphones and small cells.

This presentation will describe the antenna and package codesign for 5G NR mmwave prototype phased arrays for both handsets and small cells in the 28GHz band. Particular challenges addressed in the example packages are sub 2mm package height, low loss routing, achieving relatively large bandwidth in the antenna elements, and designing the package for small geometry RFIC with low-k dielectric back end of line.
