1. A security element that is microwave-resistant, said security element comprising:
- a first conductive trace forming a first single open loop conductor;
a second conductive trace forming a second single open loop conductor;
a dielectric layer forming a single open loop insulator and positioned between said first and second conductive traces;
said first and second conductive traces being electrically-coupled at a location that penetrates said dielectric layer; and
wherein said first conductive trace, said second conductive trace and said dielectric layer are encapsulated within plastic layers.

Abstract
A microwave-resistant and waterproof security tag for use with food products, especially meat products. The security tag includes a pair of single, open loop conductive traces in between which is disposed a similarly-shaped dielectric layer. This combination is encapsulated within plastic membranes or covers that are sealed at their common edges. The preferred embodiment includes rectangularly-shaped single, open loop conductive traces with rounded corners and with one end of each trace forming a capacitor plate. The width of each trace is at least 1/10 of the length of the security tag.
