Transmitter device for reception radiofrequency

Disclosed is a transceiving radio frequency device (10) comprising a first and a second wire conductor element (4a, 4b) forming an antenna of the device, a first transceiver chip (21) and a second loopback chip (22). The wire elements (4a, 4b) are housed in grooves (21a, 21b; 22a, 22b) formed on the first and second chip. The second chip (22) includes a loopback circuit (6 ') for electrically connecting the two wire elements (4a, 4b) with each other so that the antenna device comprises a loop. The invention also relates to a chain comprising such devices (10).
