IN Brief:
- Rohde & Schwarz will present new high-gain EMI and EMS antennas at APEMC 2026 in Kuala Lumpur.
- The R&S HF1444G14 and R&S HF1444G20 cover 14.9GHz to 44GHz for compliance and immunity testing.
- The systems address EMC demands created by higher frequencies, denser packaging, and more wireless functions.
Rohde & Schwarz will present new high-gain antennas and speed-optimised electromagnetic interference testing at APEMC 2026 in Kuala Lumpur, with systems aimed at commercial electronics, automotive systems, aerospace, and defence applications.
The company will exhibit the R&S HF1444G20 high-gain EMS antenna and the R&S HF1444G14 high-gain EMI antenna, both covering 14.9GHz to 44GHz. The antennas are designed to meet requirements under CISPR 16-1-4 and CISPR 16-2-3, with the HF1444G14 intended for full compliance testing up to 44GHz when used with the R&S ESW EMI test receiver.
For immunity work, Rohde & Schwarz will show the HF1444G20 alongside the R&S SAM200 advanced power amplifier, with support for EMS measurements under MIL-STD-461H. The company will also demonstrate speed-optimised EMI testing that generates 3D emission plots through R&S ELEKTRA test software.
The demonstration programme includes use of R&S RTO6 and MXO 5 oscilloscopes in a joint setup with EMC Partner to verify pulse output from an ESDEX high-voltage ESD generator against standards such as IEC 61000-4-2. Rohde & Schwarz engineers will also lead workshops on CISPR 32 changes for multimedia equipment, UAV electromagnetic compatibility issues in populated environments, and reverberation chamber measurement techniques.
Electronic products now combine faster digital interfaces, compact power conversion, higher-frequency radios, dense PCB layouts, and more sensors inside smaller enclosures. That combination increases the risk of emissions, susceptibility, and cross-domain interference appearing late in development.
Automotive electronics show the scale of the challenge. Electric vehicles, driver-assistance systems, radar, high-voltage inverters, onboard chargers, connectivity modules, and infotainment platforms must coexist inside a physically constrained and electrically noisy environment. EMC test methods have had to keep pace with wider frequency ranges and more complex failure mechanisms, particularly as safety-related systems become more dependent on high-speed sensing and communication.
Aerospace and defence designs add strict standards, long lifecycle expectations, platform-level integration constraints, and operation in demanding electromagnetic environments. The release of MIL-STD-461H this month places further attention on test-system readiness for laboratories supporting defence electronics qualification.
Speed-optimised EMI characterisation also changes the role of compliance work in development. Emission mapping earlier in a project can prevent late redesigns, especially where enclosure, PCB, cable, shielding, and filtering choices become expensive to change after mechanical and electrical design freeze. Three-dimensional visualisation gives engineers a clearer view of where emissions originate and how they change with configuration, frequency, and operating mode.
Shielding, filtering, grounding, layout changes, and enclosure decisions all depend on whether an issue is driven by conducted noise, radiated emissions, antenna effects, cabling, or interaction between subsystems. Faster characterisation supports a more iterative process, particularly in projects where certification schedules are tight.
As products move further into millimetre-wave operation, high-speed digital interfaces, electric mobility, and unmanned systems, EMC test capability is becoming part of mainstream electronics design rather than a final-stage specialist activity. Rohde & Schwarz’s APEMC systems bring compliance, immunity, and rapid diagnostics into a more integrated engineering workflow.
