Arched radio frequency identification (RFID) devices

A method comprising:

• providing a radio frequency identification (RFID) device comprising a sheet including a middle strip section separable from a remainder of the sheet with the middle strip section including an attachment structure, two side strips flanking the separable middle strip section, and a radio frequency circuit configured to receive RF transmissions and to transmit reply RF signals responsive to the RF transmissions, wherein the middle strip section is initially attached to the two side strips in a non-separated configuration;
• partly separating the middle strip section from two side strips flanking the middle strip section;
• and
• attaching the partly separated middle strip section to at least one of the two side strips at a corresponding at least one attachment point such that upon attaching the middle strip section, the attached middle strip section forms an arched structure protruding relative to a plane defined by the remainder of the sheet comprising the two side strips;
• wherein the middle strip section is of a length longer than respective lengths of the two side strips, wherein the middle strip section comprises an end portion protruding past end portions of the two side strips when the middle strip is in a non-separated configuration, and wherein attaching the partly separated middle strip section to the at least one of the two side strips comprises attaching one or more tabs extending transversely from the end portion of the middle strip section to the at least one of the two side strips at the corresponding at least one attachment point.
