Abstract
An antenna apparatus comprises a substrate, a chip antenna mounted on the substrate, and a ground pattern disposed on the substrate, at least a portion on the side of a power supply terminal of an antenna conductor in the chip antenna being overlapped with the ground pattern.
Claims9
An antenna apparatus comprising:
- a substrate;
- a chip antenna mounted on the substrate;
- and
- a ground pattern disposed on a portion of a surface of the substrate, wherein an antenna conductor has a first part which overlaps the ground pattern and a second part which does not overlap the ground pattern, and
- the first part includes at least a portion on the side of a power supply terminal of the antenna conductor in the chip antenna.
2 more elements
An antenna apparatus comprising:
- a chip antenna, wherein an antenna conductor has a meander shape, and said antenna conductor has a dense portion and a coarse portion in meander pitches;
- and
- a dense portion in meander pitches are provided on a power supply terminal side of the antenna conductor, and a coarse portion is provided at a tip side of the antenna conductor.
An antenna apparatus comprising:
- a chip antenna;
- and
- an antenna mount pad disposed at a position distant from an edge of a ground pattern on a substrate, wherein
- said chip antenna is mounted to direct one side having a power supply terminal to a side of the ground pattern, and to overlap the other side thereof with the pad, and
- a width of the pad is twice or less of a size in a meander width direction of a meander antenna conductor.
