Modeling Active-Integrated Antennas Co-designed with Power Amplifiers in Scanning Arrays
conference paper
We present a model of active-integrated power amplifiers (PAs) and antennas in a scanning array environment. The model combines load-pull data with unit-cell antenna simulations and a synthesized power combining network to determine the active load impedance seen by the individual transistors. The resulting output is the overall power-added efficiency, interconnect losses and radiated output power for any scan angle at a given operating frequency. The model is intended to provide a fast, first-order indication of the most suitable technology choice and design strategy for a given operating frequency and transmit power requirement
