Framework for the Cosimulation of Antenna Arrays and Receivers

This communication presents a framework for cosimulating receiving antenna arrays and receivers using circuit simulators. This framework is based on a recently introduced
2
M
-port electrical model of an
M
-element antenna array with
M
physically accessible ports and
M
“free-space” ports. Based on this framework, we describe analytical and simulator-based approaches to determine receiving-array performance metrics, such as isotropic noise response, beam-equivalent system and receiver noise temperatures, and noise-matching efficiency.
