Abstract

The improved radio wave detection technique involves detection of a diffuse signal using a differential antenna technique. The differential circuit has two parallel capacitors (2), e.g. of 4.7 microfarads, connected to a series circuit including a capacitor (3) of 8 microfarads and an inductor (4). The whole circuit is connected to the antenna socket of the radio receiver (1). An Independent claim is included for a differential antenna for a radio or TV receiver.
