Abstract
An antenna for simultaneously transmitting and receiving electromagnetic energy is disclosed. The antenna includes first and second transmit elements and a transmitter for supplying a first current to the first transmit element and a second current to the second transmit element such that the first and second transmit elements radiate electromagnetic fields. Preferably, the supplied first and second currents are substantially equal. The antenna also includes a sensor for sensing differences between currents flowing through the first and second transmit elements. The differences are caused by an electromagnetic field external to the antenna such that the antenna effectively receives the external electromagnetic field by sensing the current differences.
