This paper focused on the effects of the combined tilt to decrease the interference from overlapping sectors in urban areas. The simulation results showed that the characteristics when using a combination of mechanical up-tilt and electrical down-tilt can narrow the azimuth beam patterns. We found that the larger the mechanical up-tilt and number of(More)
A gain measurement method applied to actual measurements of fields at finite distances by using a conventional pattern measurement system and numerical compact range concept was evaluated in order to obtain the gain of a long antenna. Based on the simulation results, the dependency on the distance from an antenna array with elements in a numerical compact(More)
