Abstract (en)

[origin: EP0257544A2] Because of the geometry of a stripline antenna, this antenna can receive horizontally and vertically polarised signals (PM, PU). The received vertically polarised energy signals (PU) and the horizontally polarised data signals (PM) are demodulated separately and further processed. The energy signals are available as an operating voltage (UB) after a combined detector and voltage doubling circuit (D1,D2). The data signals are further processed as a modulated DC voltage after demodulation (D3). <IMAGE>
