A repeater device may be utilized to enable forwarding extreme high frequency (EHF) communication between EHF-enabled wireless devices. The repeater device may utilize polarization isolation to prevent and/or reduce interference between received and transmitted EHF RF signals in the repeater device. The repeater device may utilize plurality of polarization antenna arrays for reception and transmission of EHF RF signals to facilitate polarization isolation between received and transmitted EHF RF signals. Alternatively, the repeater device may utilize a single polarization antenna array, with switching elements, to facilitate polarization isolation between received and transmitted EHF RF signals. The repeater device may utilize control connections to enable communicating with the EHF-enabled wireless devices to facilitate performing polarization isolation at the repeater device. Non-EHF interfaces, for example Bluetooth, may be utilized to establish the control connections.
