1. A high temperature transponder, comprising:
- an antenna assembly, comprising;
a core comprising a first end portion, a second end portion, and a center portion between the first end portion and the second end portion, wherein each of the first end portion and the second end portion has a width greater than a width of the center portion;
an insulated antenna wire wound around the center portion of the core in a coil, the insulated antenna wire having a first wire end and a second wire end; and
an integrated circuit chip disposed on one of the first end portion or the second end portion, wherein two metal inlay portions are embedded within the chip, and wherein the first wire end and the second wire end are each connected to one of the two metal inlay portions by at least one of thermal compression, laser welding, crimp connection, soldering, or a connection adhesive;
a glass capsule enclosing the antenna assembly and defining a space between the glass capsule and the antenna assembly; and
a high temperature adhesive at least partially filling the space and covering at least 50% of the insulated antenna wire, wherein the adhesive is cured and fixes a position of the antenna assembly relative to the glass capsule.
