Abstract:
1. A signal receiving apparatus comprising a plurality of signal receiving means including: input means for inputting a broadcast wave in which a video signal and/or an audio signal are modulated in a predetermined format; a circuit board having a circuit for selecting, from the broadcast wave, a video signal and/or an audio signal included in a predetermined frequency band and demodulating the selected signals, and a mount layer on which the circuit is mounted, a first ground layer arranged, on the surface opposite to the surface on which the circuit of the mount layer is mounted, with a predetermined distance from the mount layer through a dielectric layer, and a second ground layer arranged with a predetermined distance from the first ground layer through a dielectric layer, the circuit having a microstripline structure, wherein the signal receiving means are arranged such that the lowermost ground layer of one signal receiving means and the circuit mounting surface of another signal receiving means face each other, and the signal receiving apparatus further comprising: decode means for decoding the video signal and/or audio signal that have been selected and demodulated, and output means for outputting the demodulated video signal and/or audio signal to an external device.
