Low profile antenna with horizontal polarization with tilted beam directivity and array antenna using the same

摘要

PURPOSE: A horizontal polarization plane structure antenna and a horizontal polarization plane structure array antenna using the same are provided to increase the efficiency of an antenna as well as reducing the side robe by arranging the vertical slot on a wall of wave guide tube in deviated manner. CONSTITUTION: A wave guide(112) is formed inside the waveguide(110) in longitudinal direction. A feeding unit supplies the electro magnetic wave to a wave guide of the wave guide tube. A slot is formed on a first side wall(114) of the wave guide tube in longitudinal direction of the wave guide tube. The slot is formed to be deviated to right or left of a center line which separates the first side wall of the wave guide tube.
