1. A transponder, comprising:
- an antenna assembly, comprising;
a core having a length ranging from 5 mm to 20 mm;
an insulated wire disposed around the core in a coil, the insulated wire having a first end and a second end; and
an integrated circuit chip, wherein the first end and the second end of the insulated wire are each connected to the integrated circuit chip;
a capsule enclosing the antenna assembly and defining a space between the capsule and the antenna assembly; and
a high temperature adhesive disposed within the space and covering at least 50% of the insulated wire, wherein the adhesive is cured and fixes a position of the antenna assembly relative to the capsule.
