<p>The invention relates to a maritime radar transponder comprising an omnidirectional receiving antenna (18) and a different omnidirectional transmitting antenna (19), the latter comprising n independent active wires (20) which transmit the same radar signal. The transmission channel of said transmitting antenna comprises: a first driver amplifier stage with a transistor (21); and a second amplifier stage with a Wilkinson divider bridge with n transistors (22) which are all identical to the transistor of the first stage and adapted at input and output to the antenna wires. Said transmission channel is created using a printed circuit which is directly connected to the antenna wires.</p> |
