# Industrial Specification: Internal Antenna Mounting System

## 1. Technical Definition
A precision mounting system designed to securely position and orient antennas within an EMI shielding test chamber for accurate electromagnetic interference testing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 NÂ·m torque range for mounting bolts, 0.05-0.5 mm positional tolerance, -40Â°C to +85Â°C temperature range**. Failure boundary: **Exceeding 2.5 NÂ·m torque causes thread stripping in aluminum 6061-T6 mounting plates, positional deviation beyond 1.0 mm disrupts antenna pattern integrity, temperature beyond 125Â°C degrades polymer isolators**, Mechanism: **Yield strength of aluminum 6061-T6 (276 MPa) exceeded at 2.5 NÂ·m torque causing plastic deformation; thermal expansion coefficient mismatch (23.6 Î¼m/mÂ·K for aluminum vs 70 Î¼m/mÂ·K for polymer isolators) creates stress concentrations at 125Â°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Galvanic corrosion between aluminum mounting plate and stainless steel fasteners in humid chamber environment | 8 | Increased electrical resistance at mounting interface causing antenna impedance mismatch and VSWR degradation beyond 2.0:1 | Apply MIL-PRF-23377 Type I chromate conversion coating to aluminum surfaces and use titanium fasteners with dielectric isolation washers |
| Resonant vibration at 120 Hz matching chamber cooling fan frequency | 8 | Antenna positional drift exceeding 0.5 mm during testing, introducing 3 dB pattern distortion at 18 GHz | Implement tuned mass dampers with 90 Hz natural frequency and add constrained layer damping material with loss factor Î·=0.3 to mounting brackets |
