Abstract :
A packaged microwave bipolar transistor has been integrated directly onto a rectangular microstrip patch to obtain extra power gain and to reduce power losses. The radiating element geometry has been modified to incorporate the active devices. This active antenna uses a small number of components and takes the same place as a passive antenna. An extra gain of 8 dB is obtained at 1.68 GHz.
