Abstract
According to one embodiment, an antenna apparatus includes a ground plate having an opening, a ground layer on a first side of the ground plate, an antenna on the first side of the ground plate and connected to the ground layer, the antenna being disposed around the opening, and a conductive member on the first side of the ground plate to contact an outer perimeter of the opening. The conductive member is electrically connected to the ground layer.
Claims18
An antenna apparatus disposed above an optical reader, comprising:
- a ground plate having an opening therein;
- a ground layer on a first side of the ground plate;
- an antenna on the first side of the ground plate and connected to the ground layer, the antenna being disposed around the opening;
- and
- a conductive member on the first side of the ground plate, wherein
- the conductive member is electrically connected to the ground layer and covers an entire outer perimeter of the opening so as not to substantially block light that is emitted from the optical reader, which is disposed on a second side of the ground plate opposite to the first side, and passes through the opening.
A dual-type reader apparatus, comprising:
- an optical reader for reading code symbols;
- and
- an antenna apparatus for communicating with wireless tags and comprising:
- a ground plate having an opening therein;
- an antenna on a first side of the ground plate;
- and
- a conductive member on the first side of the ground plate, wherein
- the conductive member is electrically connected to the ground layer and covers an entire outer perimeter of the opening so as not to substantially block light that is emitted from the optical reader, which is disposed on a second side of the ground plate opposite to the first side, and passes through the opening.
A reader apparatus, comprising:
- a wireless tag reader for reading information from a wireless tag attached to an item;
- an optical reader for reading code symbols attached to an item;
- and
- a controller receiving information from the wireless tag reader and the optical reader and configured to start and stop operations of wireless tag reader and the optical reader, wherein
- the wireless tag reader includes:
- a ground plate having an opening therein;
- a ground layer on a first side of the ground plate;
- an antenna on the first side of the ground plate and connected to the ground layer, the antenna being disposed around the opening;
- and
- a conductive member on the first side of the ground plate, wherein
- the conductive member is electrically connected to the ground layer and covers an entire outer perimeter of the opening so as not to substantially block light that is emitted from the optical reader, which is disposed on a second side of the ground plate opposite to the first side, and passes through the opening.
