Bluetooth Antenna
Posted by sanil.shet in Uncategorized on June 12th, 2008
BLUETOOTH is currently being introduced into several market segments, like mobile phones, headsets, PC’s etc. Bluetooth operates in the ISM-band between 2.4 GHz and 2.48 GHz and uses 80 channels, with a channel spacing of 1 MHz. Bluetooth was orginally specified in such a way that the complete system, i.e. radio and baseband, could be integrated into a single CMOS integrated circuit. This resulted in a quite poor specification for the sensitivity (-70 dBm) and output power (0 dBm, Class II) [1], [2].
In practice, it now becomes clear that systems that just meet this specification show a quite poor quality, especially for indoor voice/audio applications. There fore, the newest generation of Bluetooth BiCMOS radios show a much improved performance, with a sensitivity better than -80 dBm and output power up to +4 dBm or higher.

JasperReports is the world’s most popular open source Java reporting library. You can easily embed it into any Java application to deliver sophisticated print or web reporting. You can also use it to create output to files for further processing in applications like Excel. For users with more sophisticated report management requirements, reports designed for JasperReports can be easily migrated to the JasperSoft stand-alone report server, JasperDecisions.
