Abstract
Provided is an antenna substrate including a first substrate including a feed line and a drive patch carrying a signal received via the feed line, a second substrate laminated on top of the first substrate and including a plurality of laminated patches carrying the signal and a plurality of first pads disposed outside of the plurality of laminated patches, and a third substrate laminated on top of the second substrate and including a plurality of second pads coupled to the plurality of first pads.
Claims11
An antenna substrate comprising:
- a first substrate comprising a feed line and a drive patch carrying a signal received via the feed line;
- a second substrate laminated on top of the first substrate and comprising a plurality of laminated patches carrying the signal and a plurality of first pads disposed outside of the plurality of laminated patches;
- and
- a third substrate laminated on top of the second substrate and comprising a plurality of second pads coupled to the plurality of first pads.
An antenna apparatus comprising:
- a waveguide having a square column extending in a first direction;
- and
- a horn antenna located inside the waveguide in a coaxial configuration with the waveguide and comprising a septum,
- wherein the septum is formed based on a cross-section on a first direction side of the horn antenna to connect between two cross-sections of the horn antenna facing each other in a second direction perpendicular to the first direction along the second direction.
A device comprising:
- a plurality of antenna apparatuses;
- and
- an antenna substrate coupled to the plurality of antenna apparatuses and feeding the plurality of antenna apparatuses, wherein
- each of the plurality of antenna apparatuses comprises:
- a horn antenna comprising a septum;
- and
- a first input port and a second input port formed to be symmetrical to each other with respect to the septum corresponding to a cross-section where the septum of the horn antenna is formed,
- the antenna substrate is formed of a plurality of sub-antenna substrates coupled in one-to-one correspondence with input ports of each of the plurality of antenna apparatuses, and
- each of the plurality of sub-antenna substrates is coupled to a corresponding input port through a waveguide.
