Apparatus comprising a broadcast receiver circuit and provided with an antenna
Abstract:
The invention relates to an apparatus 1 comprising a broadcast receiver circuit, an embedded antenna for receiving broadcast signals and a tuning circuit coupled between the antenna and the receiver circuit, which tuning circuit comprises a filter circuit coupled to ground, wherein the tuning circuit is designed to have a first resonance at a first frequency below a broadcast band of interest, and a second resonance at a second frequency above the broadcast band and wherein the tuning circuit comprises an amplifier with an output to the receiver circuit and with an input to the filter circuit, and wherein the tuning circuit is provided with a carrier to noise ratio (CNR) which is substantially flat across the broadcast band.
