SBO Hearing A/S, Kongebakken 9, 2765 Smorum - DK-Denmark, CVR-no.: 39818558, www.sbohearing.com Antenna Specification The product module SBO002 is designed containing three radio interfaces: 1. A Bluetooth Low Energy transceiver operating in the band from 2402 MHz to 2480 MHz. 2. A Near Field Magnetic Induction (NFMI) transceiver operating at 3.84 MHz 3. A RFID receiver only operates in the range from 865 MHz to 928 MHz. The two transceivers are located in two different areas on the SBO002 PCB and the RFID is a received field strength powered chip glued to the PCB. The 2.4 GHz antenna for Bluetooth connections is a PCB antenna designed as an inverted F antenna. The radiation patterns are shown in annex A. The gain is measured in Cetecom Advanced GmbH test report 1-2065-25-01-06_TR1- R01 with the following gain results measured at 1 Mbps and 2 Mbps data rates: SBO Hearing A/S, Kongebakken 9, 2765 Smorum - DK-Denmark, CVR-no.: 39818558, www.sbohearing.com The maximum conducted TX power is measured to 12.0 dBm when operating at 2 Mbps, see Cetecom Advanced GmbH test report 1-2065-25-01-06_TR1-R01. The NFMI antenna is a coil antenna with 62 windings on a 1.1 mm x 1.1 mm x 4.8 mm ferrite core that is characterized in the operational description exhibit. The NFMI antenna is mounted on the PCB as a component.
