Abstract
A system for calibrating an electromagnetic navigation system is provided. The system includes an antenna assembly having a substrate, multiple pairs of transmit coils, multiple receive coils, multiple input terminals, and multiple output terminals. The substrate includes multiple layers, and each of the transmit coils is deposited on a respective one of the layers and each of the receive coils is deposited on another respective one of the layers. Each of the pairs of transmit coils corresponds to a respective one of the receive coils. Each of the transmit coils is coupled to a respective one of the input terminals, and each of the receive coils is coupled to a respective one of the output terminals.
