DUAL POLARIZATION WIDE BAND ANTENNA FOR RF COMMUNICATION

摘要

PURPOSE: A dually polarized wide-band antenna for radio frequency communication is provided to obtain a variety of radiation patterns by increasing the number of the conductive branch lines of the antenna. CONSTITUTION: Several branch lines(134) are radially installed to one vertical pylon(131). A monopole wide-band vertically-polarized radiation device(122) is arranged to the branch lines with a diamond shape in order to form an omnidirectional wide-band vertically-polarized antenna(120). A rotary support stand is installed on the upper side of the vertical pylon. A directional horizontally polarized wide-band antenna is formed. The center of the vertical pylon with the omnidirectional wide-band vertically-polarized antenna is installed on a stage(133). The branch lines are fixed to an anchor concrete(135).
