Overview

Airborne SATCOM antenna systems face a unique set of constraints that ground-based installations never encounter: aerodynamic drag, structural integration limits, rapid platform attitude changes, and strict EMI/EMC requirements.

Key Design Constraints

Aerodynamic Integration

Every antenna mounted on an aircraft creates drag. For high-speed platforms, conformal antenna designs that follow the fuselage contour are preferred. These require phased array or switched beam technology rather than conventional reflectors.

Structural Loads

Antennas must survive the full flight envelope including:

Vibration: Per RTCA DO-160G Section 8

Shock: Landing and turbulence loads

Temperature: -55°C to +70°C ambient

Moisture/Humidity: Altitude condensation

Radome Design

Radomes protect the antenna from the airstream while minimizing signal attenuation. For Ku-band (12-18 GHz), A-sandwich or C-sandwich radome constructions are standard, achieving insertion loss below 0.5 dB at nadir.

Platform Types and Solutions
