Title:
RADIATING ELEMENT, ANTENNA ARRAY, AND RADAR
Document Type and Number:
WIPO Patent Application WO/2017/200060
Kind Code:
A1
Abstract:
An antenna array according to an embodiment performs at least one of transmission and reception of an electromagnetic wave with a plurality of radiating elements. The antenna array includes a plurality of stacked waveguide components. Each waveguide component includes: an electrically conductive member having an electrically conductive surface; at least one waveguide member having an electrically-conductive waveguide face opposing the electrically conductive surface; and an artificial magnetic conductor extending on both sides of the waveguide member. A waveguiding gap between the waveguide face and the electrically conductive surface is open to an external space at an end of the waveguide face, and defines one of the plurality of radiating elements.
