Satellite Integrates Transparent Antenna Using Low-Outgassing Epoxy
Burlington, ON – May 21, 2025
MG Chemicals, a North American manufacturer of specialty chemical products for the electronics industry, is proud to support the development of next-generation satellite antenna technology with its 8330S Electrically Conductive Epoxy.
The epoxy bonds the assembly of a visibly transparent patch antenna, a novel design that integrates RF transmission capability directly onto the outer face of a satellite solar panel. This approach enables multi-functional use of external satellite surfaces, addressing the ongoing need for mass and power-efficient systems in modern space platforms.
The electrically conductive epoxy plays a critical role in the antenna’s function by electrically bonding a copper feedline to printed silver ink traces on a polyimide film. The use of 8330S eliminates the need for high-temperature soldering, which could compromise substrate materials or the silver ink traces.
A key feature of the adhesive for this application was its low outgassing, making it well-suited for vacuum environments. Adhesives like MG's 8330S and 8331S are also ideal for low Earth orbit satellites due to their EMI shielding capabilities—critical for protecting sensitive electronics from high-intensity solar radiation. The epoxy’s electrical and mechanical performance will be rigorously tested and qualified prior to launch to ensure long-term stability and reliability in orbit.
Transparent antenna technologies such as this are more than just engineering innovations—they have strategic value. When integrated into defense-related satellite platforms, they help support critical capabilities such as secure communications, Earth observation, and reconnaissance—all while minimizing interference with onboard power systems and maximizing spatial and mass efficiency. As military and intelligence agencies increasingly rely on small satellites and responsive launch platforms, multi-use components like transparent antennas offer a valuable path forward for enhancing resilience, flexibility, and mission success.
MG Chemicals is proud to contribute to this emerging class of dual-function spacecraft technologies, offering material solutions that bridge the gap between structural and electrical performance.
