ANTENNA PRODUCTS DATA SHEET 2.45 GHz ISM-band antenna for Bluetooth and WLAN IEEE 802.11b Surface-mount ceramic multilayer antennas www.phycomp-components.com Product specification Supersedes data of 5th February 2001 2001 Sep 27 Rev.1 Phycomp Product specification Surface-mount ceramic multilayer antennas FEATURES • Designed for 2.45 GHz ISM-band • Simplifies antenna circuitry • NiSn lead-free terminations • suitable for wave and reflow soldering • Supplied in tape on reel. APPLICATIONS • Telecommunications • Computing (PCs, printers, PDAs) • Wireless office data communications including WLAN • Consumer electronics (wireless headphones). DESCRIPTION 2.45 GHz ISM-band antenna for Bluetooth and WLAN IEEE 802.11b ENVIRONMENTAL CARE The foil making process uses an environmentfriendly aqueous-solvent technology that fully complies with today’s green-product design requirements. All terminations are lead-free. Packing materials can be recycled. This 2.45 GHz ceramic multilayer antenna has been designed to meet the requirements of the BluetoothTM(1) and IEEE 802.11b wireless communications protocol. It consists of a rectangular block of low-dielectric ceramic material and is fabricated in a water-based non-toxic process. The antenna is capable of providing good connectivity using near 50 Ω microstrip directly onto the PC board. (1) Bluetooth is a trademark owned by Telefonieaktiebolaget L M Ericsson, Sweden.

The antenna has built-in circuitry to the ground termination. Connecting the antenna’s ground point to the system’s RF ground plane is optional. If good matching is achieved, the ground termination is then used as a solder joint (like S1, S2, S3, and S4) to fix the antenna to the substrate only.
