摘要:
A communications device, e.g., a mobile wireless terminal, includes a plurality of antennas having different polarization directions. The plurality of antennas includes a first antenna and second antenna which are operated in a coordinated fashion. During reception a signal received via the first antenna is subjected to a phase shift operation before being combined with a signal received via the second antenna. During transmission a signal to be communicated is subjected to a phase shift operation and the phase shifted signal is transmitted over the first antenna while the non-phase shifted signal is transmitted over the second antenna. The amount of phase shift is a function of the difference in polarization directions between the first and second antennas. The novel antenna configuration facilitates the use of the horizontal polarization direction communications between the communications device and a base station without the need for directionally positioning one or more electrical antennas.
