Abstract

The invention discloses a cone-shaped beam scanning CTS antenna which comprises an H-surface ridge-adding horn (1), a Pillbox offset parabolic box (2), a U-shaped flat plate elbow (3) and a flat waveguide CTS array (4), wherein the flat waveguide CTS array is arranged above a Pillbox offset parabolic box (2); one side of flat waveguide CTS array (4) is connected with one end of the U-shaped flat plate elbow (3), of which the other end is connected with the caliber port of Pillbox offset parabolic box (2), the H-surface ridge-adding horn (1) is placed in the side wall of the Pillbox offset parabolic box (2) opposite to the reflecting surface of the Pillbox offset parabolic box (2), and the phase center aligns with a certain fixed point on the reflecting surface of the Pillbox offset parabolic box (2). According to the cone-shaped beam scanning CTS antenna, the frequency band is wide, the gain is high, and the beam is stable.

Description

technical field [0001] The invention relates to the field of microwave and millimeter wave antennas, in particular to a cone beam scanning CTS antenna with wide frequency band, high gain and stable beam. technical background [0002] The CTS (Continuous Transverse Stub) antenna reduces reflection by creating a transverse slot on the planar waveguide and placing metal baffles on the two long sides of the slot. Due to the simple feeding structure of the CTS antenna, insensitivity to processing accuracy and dielectric materials, and high radiation efficiency, it has become an important research direction for high-gain antennas. [0003] Chinese invention patent application "parabolic box fed multi-beam CTS flat panel antenna" (application number: 2017103329527, application date: 2017.05.16) discloses a parabolic box fed multi-beam CTS flat panel antenna, including a planar waveguide CTS array, two Parabolic reflector feed box and 6 waveguide horns. In this device, two identic...
