The array elements rely on open substrate-integrated waveguides, as reported previously. The paper discusses the miniaturization and optimization of these radiators. Furthermore, a concept for the integration of the active components is proposed, realized, and tested on a scaled antenna version. Simulation as well as measurement data is presented and discussed.en0149-645x201012761279Conference Paper10.1109/MWSYM.2010.5514863Other
