Antenna Array Testing Requirement Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face challenges in compliance testing of active antenna arrays due to differences in radiation correlation between antenna connection and far-field reference points, making it difficult to implement a standard approach for comparing products from different manufacturers.
Innovation Solution
A method and apparatus for translating testing requirements between different reference points by generating mapping information that relates requirements at the antenna connection point to those at the far-field point, using correlation parameters to ensure equivalent compliance performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If compliance testing is performed at the antenna connection point, then the testing is simple and direct, but it is not applicable to integrated packages where baseband circuitry and antenna array are enclosed together
Solution Approach 1:
The patent introduces mapping information as an intermediary that connects measurements at the antenna connection point to equivalent requirements at the far-field reference point. This mapping table allows testing to be performed at the accessible antenna connection point while validating performance against far-field requirements, thus resolving the contradiction between testing simplicity and applicability to integrated packages.
2Adaptability or versatility
If compliance testing is performed at the far-field reference point, then the testing applies to integrated packages, but the testing becomes complex and requires distant measurements
Solution Approach 1:
The patent creates a virtual copy of the far-field measurement scenario by using mapping information to translate far-field requirements into equivalent antenna connection point measurements. This allows the benefits of far-field testing (applicability to integrated packages) to be achieved without the practical complexities of actual far-field measurements.
3Stability of the object's composition
If the same transmitter requirements are applied at different reference points, then the requirements are consistent, but the requirements become inaccurate for active antenna arrays with uncorrelated radiation
Solution Approach 1:
The patent changes the parameters of the requirements based on the reference point being used. By using mapping information that accounts for the correlation characteristics of active antenna arrays, the system transforms far-field requirements into equivalent antenna connection point requirements, maintaining both consistency and accuracy across different reference points.

AI summary
Embodiments of the claimed subject matter provide a method and apparatus for translating testing requirements between different reference points. Some embodiments of the method include generating mapping information that relates at least one first requirement associated with an active antenna array to at least one second requirement associated with the active antenna array. The first requirements are associated with a first reference point and the second requirements are associated with a second reference point that differs from the first reference point. Some embodiments of the method also include storing the mapping information in a non-transitory computer-readable storage media.
