Abstract
The present invention concerns an antenna arrangement ( ) including: an antenna (A) able to transmit data in the form of a radiofrequency signal; a transmitter ( ) including a preamplifier ( ) and a first transistor ( ) connected in cascade, this transmitter being able to provide a radiofrequency signal containing the data to be transmitted to the antenna; and coupling means ( ) connected between the antenna and the transmitter, and including a phase lag circuit ( ) able to achieve the coupling of the antenna and the transmitter. The coupling means further include switching means ( ) connected between the system's earth and the source terminal of the first transistor of the transmitter, so as to be able to switch the latter to an ON state, respectively to an OFF state, when said antenna is, respectively is not, in transmission phase.
