Abstract
According to one embodiment, an antenna device includes a substrate; a feed element provided on or inside the substrate; a feeder line provided on or inside the substrate and configured to feed power to the feed element; and at least one of a director provided on or inside the substrate and away from the feed element, and a reflector provided on or inside the substrate and away from the feed element, wherein the substrate includes a first portion having a first thickness and a second portion having a second thickness greater than the first thickness, at least one of at least a part of the feed element and at least a part of the director is provided on or inside the first portion, and at least a part of the feeder line is provided on or inside the second portion.
Claims19
An antenna device comprising:
- a substrate;
- a feed element provided on or inside the substrate;
- a feeder line provided on or inside the substrate and configured to feed power to the feed element;
- and
- at least one of a director provided on or inside the substrate and away from the feed element, and a reflector provided on or inside the substrate and away from the feed element, wherein
- the substrate includes a first portion having a first thickness and a second portion having a second thickness greater than the first thickness,
- at least a part of either the feed element or the director is provided on or inside the first portion, and
- at least a part of the feeder line is provided on or inside the second portion,
- wherein the substrate includes the first portion and the second portion with respect to a second direction parallel to a surface of the substrate,
- the substrate is a laminated substrate of a first substrate and a second substrate having a shorter length than the first substrate in the second direction,
- the second portion is a portion where the first substrate and the second substrate are layered together, and
- the first portion is a portion of the first substrate where the second substrate is not layered.
A radar device comprising:
- a processor circuit configured to perform at least one of signal transmission processing and signal reception processing;
- and
- at least one antenna device configured to perform at least one of transmission and reception of radio waves, wherein
- the at least one antenna device comprises:
- a substrate;
- a feed element on or inside the substrate;
- a feeder line provided on or inside the substrate and configured to transmit a transmission signal from the processor circuit to the feed element or transmit a reception signal based on radio waves received at the feed element to the processor circuit;
- and
- at least one of a director provided on or inside the substrate and away from the feed element, and a reflector provided on or inside the substrate and away from the feed element,
- the substrate has a first portion having a first thickness and a second portion having a second thickness greater than the first thickness,
- at least a part of either the feed element or the director is provided on or inside the first portion, and
- at least a part of the feeder line is provided on or inside the second portion,
- wherein the substrate includes the first portion and the second portion with respect to a second direction parallel to a surface of the substrate,
- the substrate is a laminated substrate of a first substrate and a second substrate having a shorter length than the first substrate in the second direction,
- the second portion is a portion where the first substrate and the second substrate are layered together, and
- the first portion is a portion of the first substrate where the second substrate is not layered.
