L-Band RF Engineering & Antenna Design Fundamentals Training by Tonex
Master the 1–2 GHz L-Band that powers GNSS, TACCOM, IFF, and SATCOM—designing antennas and front-ends that stay reliable on ground and airborne platforms. You’ll connect propagation physics to practical antenna choices, optimize link budgets, and integrate wideband, polarization-controlled arrays into size-, weight-, and power-constrained systems. Because L-Band is a prime target in contested environments, the course frames engineering decisions through resilience: anti-jam GNSS, CRPA beamforming, and multipath-aware techniques. Security matters here—cyber-physical attacks increasingly pivot through RF paths. You’ll learn to harden architectures against spoofing, meaconing, and low-SNR abuse while aligning RF designs with cybersecurity and mission assurance goals.
