Mountains, buildings or trees that block this line of sight tend to weaken and degrade the received signal. The signal also becomes weaker as it travels further from the...
The function of antennas at base stations of cellular radio systems has been proven to be a successful way to increase the performance and the channel ability of personal communication systems. In compare to those technically highly developed base station antennas, the exterior and the practical principle of car antennas with omni directional patte...
