The Standard Gain Horn Antenna is a precision-calibrated microwave device serving as the fundamental reference in antenna measurement systems. Its design follows classical electromagnetic theory, featuring a precisely flared rectangular or circular waveguide structure that ensures predictable and stable radiation characteristics.

Key Technical Features:

Frequency Specificity: Each horn is optimized for a specific frequency band (e.g., 18-26.5 GHz)
High Calibration Accuracy: Typical gain tolerance of ±0.5 dB across operational band
Excellent Impedance Matching: VSWR typically <1.25:1
Well-Defined Pattern: Symmetric E- and H-plane radiation patterns with low sidelobes

Primary Applications:

Gain calibration standard for antenna test ranges
Reference antenna for EMC/EMI testing
Feed element for parabolic reflectors
Educational tool in electromagnetic laboratories

These antennas are manufactured under strict quality control, with their gain values traceable to national measurement standards. Their predictable performance makes them indispensable for verifying the performance of other antenna systems and measurement equipment.
