Abstract
The embodiment of the invention provides a broadband beam declination phased-array antenna, and relates to the technical field of phased-array antennae, the antenna comprises a dielectric substrate, the upper surface of the dielectric substrate is provided with antenna surface metal; a radiation slot and a U-shaped slot are etched on the antenna surface metal; the radiation slot is located on the leftmost side of the metal surface of the antenna surface layer, the U-shaped slot is located on the right side of the center line of the metal surface of the antenna surface layer, and the distance between the radiation slot and the U-shaped slot can be adjusted; and the width of the radiation slot is greater than that of the U-shaped slot. According to the technical scheme of the invention, by arranging the radiation slot and the U-shaped slot with the adjustable distance, the adjustment of the inclination angle of the wave velocity is realized, the overall structure is simple, the profile is low, and the antenna can be used in a millimeter wave frequency band with a smaller size.
