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

摘要

The horizontal polarization antenna and horizontal polarization plane structure using the same planar array antenna structure is disclosed having a directional beam tilt. Horizontal polarization plane structure antenna is coupled to one end of the waveguide and the waveguide with a waveguide formed therein in the longitudinal direction has a feeding part for feeding an electromagnetic wave to the waveguide of the waveguide, one of the two wide side walls of the waveguide of the first side wall There is a slot formed in the longitudinal direction of the waveguide, the slot is formed so as to be shifted to the left or right of the center line bisecting the first side wall of the waveguide in the longitudinal direction. According to the present invention, can at the same time that by disposed side the slot in the longitudinal direction in the wide wall of the waveguide relative to the longitudinal center line of the wave guide, it is possible to adjust the angle of the beam tilt, reducing the side lobe increasing the efficiency of the antenna is. ; Horizontal polarization, flat antenna structures, antenna arrays, beam tilt, slots
