A transmit/receive antenna for transmission and reception of electromagnetic signals. The transmit/receive antenna comprises a TX section and an RX section, where the TX section comprises a magnetically coupled TX element and a TX input terminal and the RX section comprises at least one magnetically coupled RX element and has an RX output terminal. Axes of the TX loop element and the at least one magnetically coupled RX solenoid element are parallel. Moreover, the at least one magnetically coupled RX element is positioned to provide high isolation at the RX terminal of the antenna from TX electrical signals fed to the TX input. Specifically, the at least one magnetically coupled RX element is positioned at a so that the net magnetic flux generated by the TX loop element and threading the RX solenoid element is zero.
