Title:
COUPLED FEEDING APPARATUS , PHASE SHIFTER AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/135775
Kind Code:
A1
Abstract:
Provided are a coupled feeding apparatus, a phase shifter and an antenna. The apparatus comprises a first transmission stripline and a first coupling stripline disposed on two sides of a first supporting dielectric body. An electrical connection between the first transmission stripline and the first coupling stripline is realized by means of coupling, such that the inductance-capacitance of a port can be effectively changed, thereby changing the amplitude of the port and the slope of a phase, facilitating the achievement of consistency between the amplitude and the phase dispersion, at high and low frequencies, of each output port in the phase shifter, optimizing a side lobe of a pattern of the antenna and reducing interference in a neighboring cell.
