Ultra-high frequency antenna device, ultra-high frequency antenna assembly, device method of forming such an antenna device, and support body material supply

A method of forming an ultra-high frequency (UHF) antenna device, the method comprising:

• providing a support body material supply for feeding support body material;
• forming a repetitive pattern of an antenna-wiring loop on a surface of the support body material supplied by the support body material supply, wherein the support body material has a plurality of antenna field regions, each of which being provided with an antenna-wiring loop;
• removing at least one of the plurality of antenna field regions formed on a surface of the support body material from the support body material supply;
• preparing an antenna support body on the basis of at least one removed antenna field region, wherein a partial antenna-wiring loop defining a first loop portion as an antenna-wiring pattern is formed in each removed antenna field region;
• and
• complementing the partial antenna-wiring loop into a complete UHF antenna loop by electrically coupling a second loop portion to the first loop portion, wherein the second loop portion extends at least partially outside of the antenna support body,
• wherein the partial antenna-wiring loop is obtained during or after removing the at least one antenna field region from the support body material supply when a wiring loop portion of the antenna-wiring loop is removed.
