Transmission bandwidth improvement by directive antenna in urban mobile radio communication
Tsutomu T. Takeuchi, F. Ikegami, S. Yoshida · 1986
The transmission bandwidth in urban areas determines the maximum transmission rate of digital mobile communication. A directive antenna can have an effect of broadening the transmission bandwidth by itself. The transmission bandwidth improvement of proposed antenna pattern diversity reception (APDR) is estimated by computer simulation based on the measured fading data received by directive antennas in urban areas, with two branch-switching strategies, resulting in appreciable transmission performance improvement.
