Abstract

A radio frequency (RF) antenna arrangement comprising an RF antenna element and an optical back-end. The RF antenna element comprises an electrically conductive loop, an electronic pre-amplifier and a photo-electrical conversion element. The optical back-end comprising an optical power source and a photodetector. The RF antenna element and the optical back-end being optically coupled, and wherein the optical power source is optically coupled to the photo-electrical conversion element. The photo-electrical conversion element generates upon incidence of optical power from the optical power source an electrical power signal to the pre-amplifier. The photo-electrical conversion element generates optical data signals from electrical data signals picked-up by the electrically conductive loop. The photo-electrical conversion element applies the optical data signals to the photodetector.
