Advancing wireless technology means choosing the correct antenna measurement system is increasingly important for manufacturers, research organizations, aerospace companies, defense contractors, telecommunications providers, and electronics developers. If your company develops devices related to 5G technology, satellite communications, radar, the Internet of Things, and advanced wireless technology, antenna measurement systems are necessary for the performance and regulatory standards of your products.

Organizations developing antenna measurement systems for engineers help analyze parameters including gain, radiation patterns, efficiency, and polarization. With the number of parameters that can be measured, ways to test, and configurations of the systems, choosing a system can be difficult.

DMC has published this document to help identify the most important parameters when choosing antenna measurement systems.

Why Antenna Measurement Systems Matter

The performance of modern wireless systems is heavily reliant on antennas. Even the most advanced systems of modern communications set will not perform as expected if the design of the antennas is not validated.

Precise antenna measurements enable organizations to accomplish the following:

  • Verify antenna performance
  • Improve wireless coverage
  • Reduce product development risks
  • Meet regulatory requirements
  • Ensure product reliability
  • Optimize signal quality
  • Accelerate product launches

Ambulatory measurement systems help develop validated systems by providing a means to test design iterations early in the development process to reduce the time and cost of development.

Understanding Different Types of Antenna Measurement Systems

It is important have a general knowledge of the main types of antenna measurement systems prior to selecting a system.

Measurement System Best Application Advantages
Far-Field Measurement System Large antennas, satellite systems, radar Direct measurement of radiation patterns
Near-Field Measurement System Compact test facilities, high-frequency antennas Smaller chamber requirements
Compact Range System Aerospace, defense, large antenna testing Simulates far-field conditions in limited space
OTA Testing System Smartphones, IoT, 5G devices Evaluates real-world wireless performance
mmWave Measurement System 5G, 6G, automotive radar Supports high-frequency testing

Every measurement system has its unique purpose and can be employed based on the application.

Identify Your Frequency Range Requirements

When choosing the Antenna Measurement System that best fits your needs, the operating frequency range mainly drives the choice.

Applications can differ in measurement requirements.

Sub-6 GHz Applications

  • Wi-Fi
  • IoT devices
  • Cellular communications
  • Industrial wireless systems

Millimeter Wave (mmWave) Applications

  • 5G infrastructure
  • Advanced radar systems
  • Automotive sensors
  • Satellite communications

High-Frequency Research

  • Aerospace applications
  • Defense systems
  • Future 6G technologies

Measurement systems must be designed to meet current and anticipated frequency requirements.

Evaluate Antenna Size and Product Type

Antenna size limits the options for measurement systems.

Small Devices

Examples include:

  • Smartphones
  • Wearables
  • IoT sensors
  • Wireless modules

These products often benefit from:

  • OTA testing systems
  • Compact near-field measurement systems

Medium-Sized Products

Examples include:

  • Communication equipment
  • Wireless routers
  • Base station antennas

Suitable options include:

  • Near-field systems
  • Compact range systems

Large Antennas

Examples include:

  • Satellite antennas
  • Radar systems
  • Aerospace communication antennas

These applications typically require:

  • Far-field ranges
  • Large compact range facilities

Recognizing antenna size early can help avoid unnecessary large-scale testing facilities.

Right Antenna Measurement System

Consider Measurement Accuracy Requirements

Different applications require different levels of accuracy.

Some high-performance industries demand a high level of measurement accuracy.

Industries Requiring High Accuracy

  • Aerospace
  • Defense
  • Satellite communications
  • Military radar systems

Applications with Moderate Accuracy Requirements

  • Consumer electronics
  • Smart home devices
  • IoT products
  • Commercial communication equipment

When evaluating a system, the following should be considered, as they relate to the application:

  • Dynamic range
  • Measurement uncertainty
  • Calibration capability
  • Positioning accuracy
  • Repeatability

The required accuracy level should align with product performance goals and industry standards.

Assess Chamber and Facility Requirements

The testing environment greatly impacts measurement accuracy.

Most organizations underestimate the infrastructure associated with antenna testing systems.

Key Facility Considerations

  • Available floor space
  • Chamber dimensions
  • Shielding effectiveness
  • RF absorber performance
  • Environmental control
  • Future expansion requirements

A Near-field measurement system can require far less space compared to a far-field range.

If an organization has limited facility space, compact range options can offer excellent solutions.

Determine Automation Needs

Antennas are increasingly more complex. To keep up, testing must become more efficient. Automated antenna testing provides many advantages, including:

  • Faster testing cycles
  • Reduced operator error
  • Improved repeatability
  • Higher throughput
  • Easier data analysis
  • Better reporting capabilities

Time and productivity can be greatly improved if an organization is testing a large number of systems using an automated measurement solution.

When choosing a solution, ensure software has the ability to:

  • Automated test sequences
  • Remote operation
  • Data visualization
  • Custom reporting
  • Integration with existing workflows

Evaluate Future Scalability

Because of the rapid pace of technology, future needs must be considered in the measure system being purchased today.

Consider future needs such as:

  • 5G Advanced testing
  • 6G development
  • Beamforming technologies
  • Massive MIMO systems
  • Higher frequency bands
  • Advanced OTA testing

The expense of selecting an adaptable solution is less than the expense of making a non-adaptable solution work for future needs.

Compare Total Cost of Ownership

It is important to consider the total cost of ownership (TCO) when purchasing a system.

Factors Affecting Total Cost

  • Initial equipment cost
  • Installation expenses
  • Chamber construction
  • Maintenance requirements
  • Calibration services
  • Software licensing
  • Future upgrades
  • Training costs

If a system is purchased at a lower cost but does not have the flexibility to adapt for future testing needs, it will be more costly in the long run.

Frequently Asked Questions

An antenna measurement system is a specialized testing setup used to evaluate antenna performance parameters such as gain, radiation pattern, efficiency, polarization, and directivity.

Near-field measurements are performed close to the antenna and mathematically transformed into far-field results, while far-field measurements directly evaluate radiation characteristics at larger distances.

For 5G applications, OTA testing systems, near-field measurement systems, and mmWave measurement platforms are commonly used depending on frequency and device type.

OTA testing evaluates real-world wireless performance by measuring how devices transmit and receive signals without direct cable connections.

Consider factors such as operating frequency, antenna size, measurement accuracy, chamber requirements, automation needs, scalability, and budget when selecting a system.
