DUAL POLARIZATION OMNI-DIRECTIONAL ANTENNA WITH IMPROVED COMMUNICATION QUALITY AND SIMPLIFIED MANUFACTURING PROCEDURES

摘要

PURPOSE: A dual polarization omni-directional antenna is provided to achieve improved communication quality by preventing a fading phenomenon by using a diversity technique, and simplify manufacturing procedures. CONSTITUTION: A dual 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 feeder position at two adjacent edges of the pattern so as to generate a dual polarized wave. The feeder unit is formed by arranging a circuit on the dielectric substrate. The dielectric substrate with the radiation element unit and the feeder unit formed thereon, is rolled into a cylindrical shape.
