Abstract

Radio frequency communications are effected. In accordance with one or more embodiments, a radio frequency communication circuit includes an antenna having a conductor and a semiconductor chip having a lower substrate surface coupled with the conductor to pass data carried by radio frequency signals to a radio frequency communication circuit in an active layer on an upper surface of the substrate. Accordingly, communications are facilitated via the substrate and can alleviate the need to use through-substrate connectors and further facilitate placement of the chip on the antenna.
