Overview
The PMM Antenna Suite comprises a rigorously engineered family of calibrated broadband antennas designed for precise electromagnetic field strength measurement and radiated emissions testing in electromagnetic compatibility (EMC) laboratories, regulatory test facilities, and R&D environments. Each antenna is traceably calibrated per ISO/IEC 17025 requirements and optimized for use with standardized measurement receivers, spectrum analyzers, and EMI test systems compliant with CISPR 16-1-4, ANSI C63.4, and IEC 61000-4-3. The suite supports full-spectrum coverage from 9 kHz to 6 GHz through complementary antenna types—leveraging fundamental electromagnetic principles including dipole radiation (RA-01), balanced biconical current distribution (BC-01), and self-scaling log-periodic array geometry (LP-02, LP-03)—ensuring consistent aperture efficiency, stable phase center, and minimal pattern distortion across their operational bandwidths.
Key Features
- Traceable NIST-traceable or EU-accredited calibration certificates supplied with each antenna, including amplitude correction factors (ACFs) and antenna factors (AFs) referenced to 50 Ω input impedance
- RA-01 rod antenna: optimized for low-frequency magnetic and electric field separation in the 9–30 MHz range; compact, ground-plane independent design suitable for pre-compliance surveys
- RA-01-HV variant: reinforced dielectric housing and corona-resistant construction enabling sustained operation at field strengths up to 20 kV/m (150 kHz–30 MHz), validated per IEC 61000-4-3 high-field immunity test configurations
- BC-01 biconical antenna: broadband omnidirectional response from 30–200 MHz; precision-machined copper elements ensure repeatable VSWR < 2.0 and phase stability under thermal cycling
- LP-02 and LP-03 log-periodic antennas: directional gain ≥ 6 dBi (LP-02), ≥ 8 dBi (LP-03); constant beamwidth and front-to-back ratio > 25 dB across full band; integrated balun with common-mode rejection > 30 dB
- AS-02 and AS-03 antenna sets: pre-characterized multi-antenna kits with seamless frequency handover logic, mechanical mounting adapters, and unified calibration database support for automated sweep sequencing
Sample Compatibility & Compliance
The PMM antenna series is fully compatible with standard 50 Ω RF measurement chains—including LISNs, coupling clamps, and EMC receivers—and integrates natively with commercial EMC test software platforms (e.g., EMQuest, TDEMC, EMCWare). All antennas meet mechanical and electrical requirements defined in CISPR 16-1-4:2023 Edition 4.0 for measurement antenna performance, including pattern uniformity, polarization purity, and environmental stability. RA-01-HV satisfies HV stress validation protocols outlined in IEC 61000-4-3 Annex D for high-intensity radiated field (HIRF) testing. No antenna requires active bias or external power; passive operation ensures long-term metrological stability and eliminates drift sources associated with active components.
Software & Data Management
Antenna factor (AF) and correction data are delivered in standardized .csv and .af format files, directly importable into EMC test automation frameworks supporting IEEE 1672-2021 metadata conventions. PMM provides optional Python-based calibration data parser libraries for integration into custom LabVIEW, MATLAB, or Python-based measurement pipelines. Full audit trail capability—including calibration date, technician ID, uncertainty budget breakdown (k=2), and environmental conditions during calibration—is embedded in each certificate to support GLP/GMP and FDA 21 CFR Part 11 compliance where required.
Applications
- Radiated emissions testing per CISPR 32, EN 55032, FCC Part 15 Subpart B
- Immunity verification per IEC 61000-4-3 (radiated RF field), MIL-STD-461 RS103
- Pre-compliance screening and troubleshooting in electronics development labs
- Field strength mapping for site surveys, anechoic chamber validation, and antenna placement optimization
- Calibration transfer and inter-laboratory comparison exercises under ILAC MRA frameworks
- Automated EMC test sequences requiring multi-band antenna switching without manual recalibration
FAQ
Are antenna factors provided for each unit individually?
Yes—each antenna ships with a unique, factory-measured calibration certificate listing frequency-point-specific AF values, expanded uncertainty (k=2), and traceability path to national metrology institutes.
Can these antennas be used in outdoor test sites per ANSI C63.4?
Yes—RA-01, BC-01, LP-02, and LP-03 are rated for outdoor use with IP54-rated enclosures; AS-02 and AS-03 include weather-resistant mounting hardware and cable management provisions.
Is mechanical rotation supported for azimuth/elevation scans?
All antennas feature standard 1/4″-20 and 3/8″-16 threaded mounts compatible with motorized positioners (e.g., NSI-MI, MI Technologies) and comply with CISPR 16-1-4 mechanical interface specifications.
Do you offer on-site recalibration services?
PMM-certified calibration partners operate globally across North America, EMEA, and APAC; scheduled recalibration intervals follow ISO/IEC 17025 recommendations (typically every 12–24 months depending on usage intensity).
