DISTRIBUTED ON-PACKAGE MILLIMETER-WAVE RADIO

摘要

Embodiments described herein generally relate to phased array antenna systems or packages and techniques of making and using the systems and packages. A phased array antenna package may include a distributed phased array antenna comprising (1) a plurality of antenna sub-arrays, which may each include a plurality of antennas, (2) a plurality of Radio Frequency Dies (RFDs), each of the RFDs located proximate and electrically coupled by a trace of a plurality of traces to a corresponding antenna sub-array of the plurality of antenna sub-arrays, and (3) wherein each trace of the plurality of traces configured to electrically couple an antenna of the plurality of antennas to the RFD located proximate the antenna, wherein each trace of the plurality of traces is configured to transmit millimeter wave (mm-wave) radio signals, and wherein the plurality of traces are each of a substantially uniform length.

1. A package comprising:
a distributed phased array antenna comprising:
a plurality of antenna sub-arrays, each sub-array comprising a plurality of antennas;a plurality of Radio Frequency Dies (RFDs), each of the RFDs located proximate and electrically coupled to a plurality of traces to a corresponding antenna sub-array; andwherein each trace of the plurality of traces is configured to electrically couple an antenna of the plurality of antennas to the RFD located proximate the antenna, wherein each trace of the plurality of traces is configured to transmit millimeter wave (mm-wave) radio signals, and wherein a maximum difference in length between traces is no more than two wavelengths of a signal being carried by the traces.
