In an antenna unit provided to amplify a received signal and retransmit the same signal amplified the antennas are formed directly on an integrated circuit. In a preferred embodiment the antennas are directional patch antennas which are provided at different sides of the integrated circuit, whereby the integrated circuit itself acts as an isolator between the two antennas. By means of locating the antennas directly on the integrated circuit lines between the antenna and the amplifier are avoided, which in turn significantly reduces the attenuation which takes place in conventional repeaters and the like. |
