MASTRAD markets in particular a MEAT°IT connected kitchen thermometer. This product includes a rechargeable temperature probe with a Bluetooth Low Energy (BLE) interface, and a charging base that also serves as a BLE relay to the user's smartphone. MASTRAD is currently developing a new version of this product using PCB Antenna on the Repeater. In this context, MASTRAD asked ALCIOM for an expert report intended to BLE performance of the PCB Antenna. This document presents all the work carried out by ALCIOM in response to this request.

Two radiation peaks are observed around the 0° and 180° angles. The power radiated by the base is around 8dBm. Communication is optimal if the probe is placed at a 90° angle from the base (this maximizes the direct path and the multi-paths that arrive at 90+/-45° angles from the base). p to a distance of 2 mm) Machine Translated by Google Mastrad XW3 Product BLE Performance Analysis Reference: AL/CH/2115/001 Edition:1A Page: 6/18 Machine Translated by Google Mastrad XW3 Product BLE Performance Analysis Reference: AL/CH/2115/001 Edition:1A Page: 7/18 3 Conclusions The results obtained in this work can be summarized as follows: For the base: - Radiation is maximum for angles around 90°, it is greater than rear radiation (270°) by at least minus 3dB. Two radiation peaks are observed around the 0° and 180° angles. The maximum power radiated is of the order of 8dBm - Communication is optimal if the probe is placed at a 90° angle from the base (this maximizes the direct path and the multi-paths which arrive at angles 90+/-45° from the base). Drive power: The driving powers of the two modules are almost the same (about 3.3 dBm). The difference in reach communication is therefore not linked to the electrical power supplied by the BLE chips.
