Glossary

EIRP: Effective Isotropic Radiated Power — the power transmitted by an isotropic antenna to produce the same signal strength.

G/T: Figure of Merit — ratio of antenna gain to system noise temperature, indicating receive performance.

RHCP / LHCP: Right-Hand / Left-Hand Circular Polarization.

Radiation-hardened: Designed to withstand ionizing radiation in space environment (e.g., protons, electrons, heavy ions).

Multi-beam Positioning: Ability to form and steer multiple independent beams simultaneously for spatial coverage or tracking.

SMA: SubMiniature version A — a coaxial RF connector rated up to 18 GHz.

Micro-D: A miniature D-sub connector series widely used in aerospace and military applications.

MDM: Microminiature D connector series conforming to MIL-DTL-83513.

MIL-D-38999: U.S. military standard for high-performance circular connectors (TVS06RF series).

EN4644: European standard for micro rectangular connectors used in aerospace applications.

J30JA / J36A: Chinese national defense standard (GJB) micro rectangular connector series.

Flat Panel Design: Low-profile, planar antenna array suitable for satellite body mounting with minimal protrusion.
