Lire la suite >A continuously steerable beam patch antenna array employing a classical phase shifter based on GaN HEMTs is presented. Here the GaN HEMTs are used as varactor diodes to achieve the tunability purpose. By controlling the DC bias of these varactors from -2 V to 2 V, the proposed array antenna can provide continuous beam steering from 0• to +25• in the azimuth plane at 41.20 GHz, while achieving low side lobe level and good impedance matching performances. Using GaN HEMTs as varactors to achieve the beam steering capability has never been tried before from our acknowledgment. Measurement results agree well with the simulation results and validate the effectiveness of the proposed beam steering based on GaN technology. This proposed phased array antenna will find numerous applications within future wireless communication systems especially for millimeter-wave applications.Lire moins >
