WIRELESS DEVICE WITH 3-D ANTENNA SYSTEM

摘要

Techniques for improving coverage of an antenna system are disclosed. In an aspect, a wireless device includes a 3-D antenna system to improve coverage and enhance performance. The 3-D antenna system includes antenna elements formed on multiple planes pointing in different spatial directions. Antenna elements formed on the multiple planes are associated with different antenna beams, which can provide a larger line-of-sight (LOS) coverage for the wireless device. Beamforming may be performed for the antennas on a given plane to further improve LOS coverage. Non-LOS (NLOS) coverage may also improve since antenna beams pointing in different spatial directions may result in reflected signals of higher power levels due to better signal reflection for some antenna beams.
