Dual Polarized Base Station Antennas For Polarization Diversity systemsDual Polarized Base Station Antennas For Polarization Diversity Systems
It is well known that in a cellular network, mobile phones have considerably lower transmittal power than the transmitters of the base stations. This means that the transmission from the mobile phone to the base station (uplink) is much more unfavorable in relation to the transmission from the base station to the mobile phone (downlink). To compensate this, a way of improving the quality of reception at base stations had to be found. Due to the multi-path signal propagation of radio signals, which occurs in urban areas, so called Space Diversity Reception has been introduced which provides the best results in the field. Space Diversity Reception is based on the following idea: The signal transmitted by a mobile phone i
