Patent ID: 7400871

Claim:
A multi-antenna receiving and processing circuit assembly comprising: a plurality of antennas for receiving wireless signals; a plurality of pre-processing units respectively electrically connected to said antennas; a matching circuit electrically connected to said pre-processing units and adapted to match signals from said pre-processing units into a matching signal, wherein a connection of the matching circuit to the pre-processing units includes a capacitor connected to each of the pre-processing units, a capacity ground at a front side of each said capacitor, and two inductors connected in series at a rear side of each said capacitor, said connection further including a resistor connected between said inductors, and a capacitor connected to two ends of said resistor; a post-processing unit electrically connected to said matching circuit and adapted to process said matching signal from said matching circuit through a single intermediate frequency signal and then a plurality of audio frequency signals respective to each antenna; and an output circuit electrically connected to said post-processing unit for outputting said audio frequency signals to external audio output means.
