Co-Designed Handset Antennas with Wide Angular mm-Wave Coverage and LTE MIMO

Abstract

The coexistence of mm-wave and LTE antennas in modern handsets is yet an unsolved challenge in the phone industry and antenna research community. The different antenna types merged together in a shared volume easily hinder each other's performance. This paper extends the work published recently, showing how high-gain mm-wave antennas at 28 GHz can be incorporated in the same volume with LTE MIMO antennas. The results show that with small compromises a decent performance can be achieved at both mm-wave and LTE bands.
