Abstract
A system including a device with a first chip and a device with a second chip, to realize contactless communication therebetween. The first chip includes a transmitter circuit converting parallel data into a differential signal and a transmitting antenna transmitting the signal to the second chip. The second chip includes a receiving antenna receiving the differential signal from the transmitting antenna and a receiver circuit converting the differential signal into the parallel data. The transmitting and receiving antenna each include at least two antenna elements, first and second terminals, and first and second junctions. The antenna elements consist of wiring lines on the chips. The terminals are connected with circuits on the chips. At the first junction, first ends of the antenna elements meet to connect to the first terminal. At the second junction, second ends of the antenna elements meet to connect to the second terminal.
