VERTICAL POLARIZATION OMNI-DIRECTIONAL ANTENNA AND HORIZONTAL POLARIZATION OMNI-DIRECTIONAL ANTENNA USING DIELECTRIC SUBSTRATE, CAPABLE OF IMPROVING COMMUNICATION QUALITY BY PREVENTING FADING PHENOMENON

摘要

PURPOSE: A vertical polarization omni-directional antenna and a horizontal polarization omni-directional antenna are provided to allow for a mass production of antennas having uniform characteristics, and improve communication quality by preventing a fading phenomenon through the use of a space diversity method and a polarization diversity method. CONSTITUTION: A vertical polarization omni-directional antenna comprises a radiation element unit for receiving signals from a terminal, and transmitting the signal generated from a base station equipment or a relay to a free space; a feeder unit for transmitting, impedance matching and distributing input/output signals; and an input/output connector for inputting the energy transmitted through the feeder unit to the base station equipment or relay. The radiation element unit is made by forming a square patch antenna pattern on a dielectric substrate(20) having a metal film, and arranging a feeding position at the center of the bottom or top of the pattern so as to generate a vertically polarized wave. The feeder unit is formed by arranging a circuit on the dielectric substrate. The dielectric substrate on which the radiation element unit and the feeder unit are formed, is rolled into a cylindrical shape.
