QUICK REFERENCE DATA DESCRIPTION Centre frequency (for different central frequency shifts) Bandwidth Gain VSWR Polarization Azimuth beamwidth Impedance Power dissipation Operating temperature Terminations Resistance to soldering heat Weight 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. 2002 Oct 17 Rev.2 3 www.yageo.com Phycomp Product specification Surface-mount ceramic multilayer antennas ELECTRICAL CHARACTERISTICS DESCRIPTION Centre frequency Bandwidth Gain VSWR Polarization Azimuth beamwidth Impedance Power dissipation Operating temperature Terminations Resistance to soldering heat FOOTPRINT DIMENSIONS L C 2.45 GHz ISM-band antenna for Bluetooth and WLAN IEEE 802.11b VALUE 2.45, 2.60, 2.70, 2.80 and 2.90 GHz 100 MHz 1.2 dBi max. 2 max.
