Container provided with RFID module and method for manufacturing container provided with RFID module

A container including an RFID device, the container comprising:

• a base having an insulating property and configured to form an outer shape of the container;
• and
• an antenna pattern including a first antenna film including a first length and a first pattern and a second antenna film including a second length and a second pattern on a first main surface of the base,
• wherein the RFID device includes:
• an RFIC element,
• a filter,
• a first electrode electrically connected to the first antenna film, and
• a second electrode electrically connected to the second antenna film,
• wherein a sheet resistance of each of the first antenna film and the second antenna film is 0.5Ω/sq or more;
• wherein the second length and the first length are different or the first pattern and the second pattern are different.

A method for manufacturing a container including an RFID device, the method comprising:

• printing an antenna pattern including a first antenna film including a first length and a first pattern and a second antenna film including a second length and a second pattern on a first main surface of a base having an insulating property and that forms an outer shape of the container;
• and
• mounting the RFID device that includes an RFIC element, a filter configured to transmit a current due to an electromagnetic wave to the RFIC element, and first and second electrodes to be connected to the filter on the first antenna film and the second antenna film so as to electrically connect the first electrode and the first antenna film and to electrically connect the second electrode and the second antenna film,
• wherein a sheet resistance of each of the first antenna film and the second antenna film is 0.5Ω/sq or more;
• wherein the second length and the first length are different or the first pattern and the second pattern are different.
