Abstract
A communication circuit according to one embodiment includes a single element antenna, a plurality of signal-limiting circuits, a high-frequency transceiver circuit, and a low-frequency transceiver circuit. The high-frequency transceiver circuit is adapted to be selectively coupled to the single element antenna via the plurality of signal-limiting circuits and tuned to operate at a high frequency carrier frequency, and the low-frequency transceiver circuit is adapted to be selectively coupled to the single element antenna via the plurality of signal-limiting circuits and tuned to operate at a low frequency carrier frequency.
