Phased Array Antenna Engineering for Space Applications

Phased array antennas are among the most important enabling technologies for modern space communications, and this book provides a practical, system-minded guide to designing, modeling, calibrating, and verifying them for orbital missions. It brings together the electrical, mechanical, thermal, and operational factors that shape real spacecraft antenna performance, with a clear focus on beam steering, multi-beam coverage, and space qualification.

Readers are guided from mission requirements to implementation details, including link budgets, EIRP and G/T targets, polarization control, spacecraft constraints, and spectrum/regulatory concerns. The text then builds the core principles of array synthesis, showing how element patterns, weighting, phase control, and time-delay techniques influence beam shape, scan range, sidelobes, and wideband behavior.

Key topics covered

• Array architectures for single-beam, multi-beam, analog, hybrid, and fully digital systems
• Element design, RF front-end integration, and packaging for space use
• Phase shifters, attenuators, true-time-delay methods, and beamforming networks
• Calibration, drift correction, beam squint compensation, and in-orbit maintenance
• Modeling, simulation, test methods, and acceptance planning for qualification
• Signal processing methods for beam control and interference suppression

The book also addresses practical engineering realities such as thermal drift, vibration, radiation exposure, component nonidealities, measurement uncertainty, and control-timing issues. Each major section ties theory to execution, helping readers understand how design choices affect gain, coverage, isolation, and long-term reliability.

Ideal for antenna engineers, RF system designers, spacecraft payload teams, and advanced students, this volume serves as both a technical reference and an implementation guide. Its case studies and step-by-step workflows make it especially useful for teams moving from requirements definition to hardware build, test, calibration, and final mission readiness.
