Abstract
The invention relates to the fabrication of radiofrequency transmission/reception devices. The invention makes provision for: the making of radiofrequency transmission/reception chips devoid of antennas; the connecting in series of the chips by at least two conducting wire elements whose respective lengths between two neighboring chips are chosen as a function of the transmission/reception frequency, each element contacting electrically at least one terminal of a chip and ensuring an at least temporary function of mechanical holding of the chips chainwise; and the cutting at regular intervals of the serial connection to form, for each chip, two strands of an antenna of the device.
Claims15
A method for manufacturing radio frequency transceiver devices, comprising:
- forming of radio frequency transceiver chips having no antennas;
- serially connecting the chips, the chips being connected to each other or to an intermediary element between two chips by at least two conductive cable elements, wherein the at least two conductive cable elements have their respective lengths selected according to the transmission-reception frequency, and each conductive cable element electrically contacting at least one terminal of a chip and at least temporarily mechanically maintaining the chips chained;
- and
- cutting at regular intervals of the series connection to form, for each chip, the strands of an antenna of the device.
A chain of radio frequency transceiver devices, comprising several electronic chips integrating radio frequency transceiver circuits and connected to one another, the chips being connected to each other or to an intermediary element between two chips by at least two conductive cable elements connected to antenna connection pads of the chips, wherein the at least two conductive cable elements have their respective lengths selected according to the transmission-reception frequency.
