Active Integrated Antennas with Single and Push-Pull Transistor Oscillators

The paper presents the R&D in the field of active integrated antennas at the University of Zagreb. Several prototypes with single transistor oscillator and two-transistor push-pull oscillator are designed, manufactured and subjected to experimental verification of their characteristics. Rectangular, square and circular microstrip patches are used. The possibility of obtaining linear and circular polarizations is investigated. Integration of several active antennas in mutually injection locked antenna arrays is studied. Power combining and beam scanning capabilities are demonstrated.
