Sony patents antenna system that finds signal direction with fewer wires

Patent drawing from the official filing.

Sony describes a radio receiver that connects multiple antenna elements in a single line to reduce wiring. It compares the signals from each element to a known reference to calculate the exact direction the radio wave is coming from.

Why it mattersThis design could make it easier to build compact devices that need to pinpoint the location of a signal source, such as in-car sensors or specialized communication hardware.

In the filing’s own words

Provided is a reception device including: an antenna component including a plurality of antenna elements that receives a predetermined radio wave transmitted from a predetermined transmission device, and a transmission line that connects the plurality of antenna elements in series and transmits a radio wave received by each of the antenna elements; a correlator that acquires the radio wave via the transmission line and calculates a correlation between the radio wave received by each of the antenna elements and the predetermined radio wave; and an arrival direction calculation unit that calculates an arrival direction of the radio wave on the basis of the calculated correlation.

What exactly they claim (claim 1)

1. A reception device comprising: an antenna component including a plurality of antenna elements that receives a predetermined radio wave transmitted from a predetermined transmission device, and a transmission line that connects the plurality of antenna elements in series and transmits a radio wave received by each of the antenna elements; a correlator that acquires the radio wave via the transmission line and calculates a correlation between the radio wave received by each of the antenna elements and the predetermined radio wave; and an arrival direction calculation unit that calculates an arrival direction of the radio wave on the basis of the calculated correlation.
