Bluetooth™ multilayer ceramic antenna				Easy design-in The surface-mount antenna can be mounted directly on a PC board using either reflow or wave soldering. Compared with traditional external antennas, it can eliminate the use of expensive RF connectors and coaxial cables (replaced by near 50 O microstrip line directly on the PC board). The broad bandwidth and standard 50 O impedance matching minimizes changes in the electrical properties due to differences in mounting conditions of the antenna. The antenna can be located close to the Bluetooth RF module to reduce signal loss. The antenna's broad bandwidth also makes it is insensitive to small deviations in center frequency and simplifies the antenna circuitry by reducing the need for customized tuning.		allow the development of compact Bluetooth/WLAN products offering optimum RF performance. Practical tests have conclusively shown that the antenna is easily capable of providing good Bluetooth connectivity using 42 to 58 O impedance matching based on inexpensive microstrip line.
Phycomp has expanded its product portfolio with a brand new multilayer ceramic antenna. With dimension of 7.3 x 5.5 x 1.4 mm and a weight of 0.16 g the new product is one of the world's smallest broadband full-performance antenna solutions for Bluetooth* and wireless LAN applications. Despite its ultra-small size, the new antenna can still provide high gain of 1.2 (dBi) and broad bandwidth up to 100 MHz to 140 MHz for use in the 2.4 GHz ISM band.			Applications The antenna is a key component in Bluetooth applications. Bluetooth is an open protocol for short-range wireless communication in the 2.4 GHz ISM band. It enables electronic devices to communicate with each other without conscious user intervention. The market for devices equipped with Bluetooth is expected to boom in the coming years driven by applications that target a "world without cables". Examples of Bluetooth break-through applications are wireless links between laptops and cellular phones (enabling an internet link), wireless links between cellular phones and headsets and wireless links between computers or cell phones to printers enabling wireless printing.
						Environment-friendly design Under its blue surface, the new antenna embodies a host of environment-friendly features developed using Phycomp's technological strength in "green" processes. The surface-mount Bluetooth antenna is manufactured with low-dielectric material and uses Phycomp's unique water-based non-toxic production process and lead-free terminations. It therefore fully complies with today's demanding green-product design requirements. Additionally, the product is sintered at low temperature, which consumes less energy in manufacture, and the use of co-firing using the company/is low temperature co-fired ceramic (LTCC) technology further reduces manufacturing energy consumption.

Fig.1 Innovation and "green" design are principal features of Phycomp's new multilayer ceramic antennas for Bluetooth/WLAN applications The development stems from the company's focus on providing innovative solutions to the telecommunication and data-processing industries. It's based, in particular on the use of advanced computer-aided RF design tools combined with Phycomp's acknowledged expertise in both MLCC and R-chip manufacturing and material technologies.					More Phycomp innovations in the pipeline With its extensive material and manufacturing experience, Phycomp will continue to provide internal antenna solutions for other telecommunication market segments. The company is currently active in the development of internal antennas for GPS and dual-band GSM antenna solutions.

		Whilst initially developed for Bluetooth applications, the Phycomp antenna can also be used for Wireless LAN data communication.		Fig.4 H-plane top (omni-directional) and E-plane bottom With a maximum VSWR of 2.0, it easily covers the extended frequency range of 2.4 to 2.5 GHz required by the Bluetooth standard. In addition, its high gain and omnidirectional characteristics (H-plane) overcomes limitations due to the housing, metal shielding, LCD drive circuitry, PC board ground planes and microstrip line quality, to		For more information visit out website at: http://Www.phycomp-components.com * Bluetooth is a trademark owned by Telefonieaktiebolaget L M Ericsson, Sweden
