Antenna-radome interaction of 2GHz band 120/spl deg/ beam antenna

The purpose of this study is to investigate input and radiation characteristics of antennas due to parameters of the dielectric cylindrical radome. Sector antennas occupy an important position in base station antennas. It is necessary to investigate the radome effect for sector antennas. In this paper, we investigate the input and radiation characteristic of a 2 GHz band 120/spl deg/ beam antenna due to the radome's parameters.
