Antenna Radiation Tests
Unveiling True Antenna Performance
At Antennity, we understand that comprehensive antenna evaluation goes beyond basic return loss measurements. Our radiation pattern testing service provides crucial insights into your antenna’s real-world performance, ensuring your IoT devices meet both regulatory requirements and network operator standards.
Beyond Return Loss
While a favourable return loss is important, it doesn’t tell the whole story:
- Directional Performance: Understand how your antenna radiates in all directions
- Efficiency Measurement: Determine how much input power is actually radiated
- Gain Characterisation: Identify areas of strong and weak signal propagation
Critical for Compliance and Optimisation
Radiation pattern tests are essential for several reasons:
- Network Operator Requirements: Many carriers mandate TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity) measurements
- PTCRB Certification: Necessary for devices operating on cellular networks
- Performance Optimisation: Identify and address areas of suboptimal radiation
Our Comprehensive Testing Approach
We offer a thorough radiation pattern testing service:
- 3 Axis Pattern Measurement: Full spherical radiation pattern characterisation
- Multiple Frequencies: Testing across all relevant frequency bands

Case Study: Wearable Device Optimisation
A client developing a cellular-connected health monitor faced challenges with network certification:
- Initial TRP measurements fell below carrier requirements
- Our radiation pattern tests revealed significant body-blocking effects
- We recommended antenna repositioning and tuning adjustments
Result: After implementing our suggestions, the device passed carrier certification, saving months of potential delays and redesign costs.
Meeting Network Operator Standards
Many network operators have strict requirements:
- TRP Thresholds: Ensure sufficient power output for reliable connections
- TIS Requirements: Validate receiver sensitivity for optimal data reception
- Band-Specific Criteria: Meet performance standards across all supported frequency bands
Our testing helps you meet these critical benchmarks, smoothing the path to network approval and device certification.
PTCRB Certification Support
For cellular IoT devices, PTCRB certification is often mandatory:
- We provide all necessary radiation pattern data for submission
- Our experts guide you through the certification process
- We offer pre-testing to identify and address issues before formal certification
Beyond Compliance: Performance Optimisation
While meeting standards is crucial, our goal is to help you excel:
- Identify Performance Gaps: Pinpoint areas where your antenna underperforms
- Optimisation Strategies: Suggest design modifications for improved radiation
- Iterative Testing: Support through multiple design iterations if needed
Comprehensive Reporting
Our test reports provide a wealth of information:
- Detailed 3D Radiation Plots: Visualise your antenna’s performance
- Efficiency Calculations: Understand how effectively your antenna radiates
- Gain Tables: Quantify performance across different angles and frequencies
- Compliance Summary: Clear indication of pass/fail status for relevant standards
