Title:
HIGH-OUTPUT SLOT WAVEGUIDE ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/080529
Kind Code:
A1
Abstract:
The present invention relates to a high-output slot waveguide array antenna and, more particularly, to a high-output slot waveguide array antenna having a structure capable of transmitting high-output radio waves to a specific object and enabling a stable operation by preventing breakdown or the like due to high output. The present invention provides a slotted-array antenna comprising: a power distribution unit which distributes a radio wave input through a radio wave input port to first and second waveguides of a first level, and then distributes the radio wave from the first waveguide of the first level to first and second waveguides of a second level, and distributes the second waveguide of the first level to third and fourth waveguides of the second level; a feeding unit which feeds the radio wave distributed to the first to fourth waveguides of the second level to multiple radiation waveguides through multiple feeding slots; and a slotted-array radiation unit which radiates the radio wave fed to the multiple radiation waveguides to the outside through multiple radiation slots.
