In addition to providing wireless modules, KAGA FEI also
provides antenna characteristics measurement service to ensure that the module's radio
characteristics are fully exhibited.
We offer a wide
range of services such as antenna characteristics measurement on end product and provision of
measurement data.
Even if the wireless module is incorporated into the end product, it is meaningless if the wireless connection becomes difficult because it is inserted into the housing. The circuit board and housing around the antenna of the wireless module, and human hands affect the radio wave characteristics and affect the communication distance of the product. Also, if the outer shape of the product is given priority, it is not always possible to implement the module under ideal wireless conditions.
Therefore, it is valuable to get the antenna measurement support that can confirm the radiation pattern in the product or in the prototype.
KAGA FEI aims to achieve both product design
and wireless performance!
*This support is a paid service exclusively for customers who have purchased our wireless modules.
To achieve optimal performance of the wireless module, consider these two main points:
Advice from the Product Design Stage
We believe reviewing designs before finalizing product specifications is essential. The wireless module’s radio characteristics are affected by the surrounding board and housing.
Therefore, if requested, we may ask you for design information of the board implementing the wireless module and details about the relevant information of your product at the stage when the product’s appearance and board layout are being considered.
Within the requested conditions, our technical team will work with you to determine the best implementation position, orientation, or product housing shape to maximize radio characteristics.
>>>We offer product design advice via email and phone, so feel free to reach out.
＊Review meetings with our technical team are also available if needed.
Verification of Wireless Characteristics and Feedback
We use a "near-field multi-probe measurement system" to measure radio
characteristics in a short time.
Generally, when measuring in an anechoic
chamber, radio characteristics are measured in the three XYZ axes in
multiple steps. This system, however, can measure the radio characteristics
in all three axes in a single measurement, thus reducing measurement time
and allowing for more pattern data within a limited time frame.
＊About the Near-Field Multi-Probe Measurement System
The antenna mounted on the end product to be measured emits radio waves, which is the measured signal. As the table of the measurement system with the end product on it rotates, multiple sensors around it receive the waves, and dedicated software calculates the antenna characteristics and displays them as a 3D radiation pattern.
[System Overview]
・Frequency range: 650 MHz
to 6 GHz
・ Measurable objects:
- Size: Max 0.45 m
- Weight: Max 10 kg
The measurement results are provided as a report. You can check the data against the expected wireless characteristics at the product design and provide feedback on the design. Through actual product testing and fine adjustments, you can determine the best implementation position and orientation of the module to ensure the antenna performance.
[Report Results Include]
・ VSWR
・ Antenna
Efficiency and Gain
・ Radiation Pattern
