Abstract

A system comprising: an interrogator device, comprising: a first transmit antenna configured to transmit radio-frequency (RF) signals circularly polarized in a first rotational direction; and a first receive antenna configured to receive RF signals circularly polarized in a second rotational direction different from the first rotational direction; and a target device, comprising: a second receive antenna configured to receive RF signals circularly polarized in the first rotational direction and a second transmit antenna configured to transmit, to the interrogator device, RF signals circularly polarized in the second rotational direction.
