Active antenna for mobile commucation

TLDR: In this article, an active antenna for mobile communication is provided to increase the efficiency of an antenna by reducing the transmission loss between a base station and an antenna, which is composed of a diversity antenna(110), a transmitting and receiving relay, and a coaxial cable.

Abstract: PURPOSE: An active antenna for mobile communication is provided to increasing the efficiency of an antenna by reducing the transmission loss between a base station and an antenna CONSTITUTION: An active antenna for mobile communication is comprised of a diversity antenna(110), a transmitting and receiving relay, and a coaxial cable The transmitting and receiving relay is connected to the diversity antenna with a coaxial cable and is connected to an optical delay with an optical cable The transmitting and receiving relay converts an optical signal and a high frequency signal mutually and relays a signal for a G3 and Wibro service
