We would like to introduce a case study of IoT development that our company has conducted. When considering an antenna for a AA battery-type BLE device, the antenna space is limited, and a AAA battery is located in close proximity, making it difficult to adjust with a standard chip antenna. We developed a pattern antenna that takes into account the influence of the circuit board and battery, meeting the operational specifications. In addition, we also have a case study of the development of an automatic audio guide system for aquariums that realizes automatic switching of explanation areas. 【Case Overview】 ■ Issues - The antenna space is limited when considering an antenna for a AA battery-type BLE device. - Due to the close proximity of a AAA battery, adjustment with a standard chip antenna is difficult. ■ Results - Developed a pattern antenna that considers the influence of the circuit board and battery, meeting the operational specifications. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of IoT development that our company conducted. In a communication carrier certification test for a commercial tablet, the receiving sensitivity could not meet the standards due to internal noise in the device. Therefore, we reviewed the circuit board wiring, strengthened the ground, and enhanced the shielding to suppress the noise, which improved the receiving sensitivity and allowed us to pass the test. Additionally, we have a case where EMV (Europay, Mastercard, and Visa) certification was obtained for a commercial tablet. [Case Overview] ■ Issues - It was necessary to obtain certification from the communication carrier, but the receiving sensitivity could not meet the standards due to internal noise in the device. ■ Results - By reviewing the board wiring, strengthening the ground, and enhancing the shielding, we were able to suppress the noise and improve the receiving sensitivity, successfully passing the test. *For more details, please refer to the PDF document or feel free to contact us.
