Abstract
In this article, we present a low-power, small form-
factor, 60-GHz packaged radio featuring broad beam coverage.
We increase angular coverage by beam switching between two
orthogonally pointed low directivity beams that are created using
two different antennas integrated in package. The resulting wide
angular coverage of the radio makes radio links robust to move-
ment and rotation; this improvement overcomes a key challenge
for millimeter-wave (mmWave) deployment in portable electron-
ics. We
