In some embodiments, interrogator transmit antenna 524 may be configured to transmit RF signals circularly polarized in a first rotational direction (e.g., clockwise) and the interrogator receive antenna 526 may be configured to receive RF signals circularly polarized RF in a second rotational direction different from the first rotational direction (e.g., counter-clockwise). Additionally, in some embodiments, the target device receive antenna 528 may be configured to receive RF signal circularly polarized in the first rotational direction and the target device transmit antenna 530 may be configured to transmit RF signals circularly polarized in the second rotational direction. Accordingly, in some embodiments, the interrogator transmit antenna 524 and the target device receive antenna 530 may be configured to transmit/receive RF signals circularly polarized in the same direction. Likewise, target device transmit antenna 528 and interrogator receive antenna 526 may be configured to transmit/receive RF signals circularly polarized in the same direction.
