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. 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. • 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).

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 2.45 GHz ISM-band antenna for Bluetooth and WLAN IEEE 802.11b ELECTRICAL CHARACTERISTICS DESCRIPTION VALUE Centre frequency 2.45, 2.60, 2.70, 2.80 and 2.90 GHz Bandwidth 100 MHz Gain 1.2 dBi max.

Basic dimensions are given in Figs 7 and 8, and Tables 4 and 5. • Cover tape, carrier tape and reel do not contain environmentally-harmful PVC materials. • Because the carrier tape is made of polycarbonate, a homogeneous material (mono-plastic), it is ideally suited for recycling. Peel-off force • Compared to other PVC-free materials polycarbonate shows excellent stiffness and very little deformation with temperature. Peel-off force of the blister tape is in accordance with “IEC 60286-3”; that is, at a peel-off speed of 300 ±10 mm/minute, 0.1 N to 1.3 N for 16 mm tape. The peel-off angle should be between 165° and 180°.
