2.45 GHz ISM-band antenna for Bluetooth
and WLAN IEEE 802.11b (Long Shape)
DESCRIPTION
This 2.45 GHz ceramic multilayer
antenna has been designed to meet
the requirements of the Bluetooth
TM(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
W
microstrip directly onto the PC board.
ENVIRONMENTAL CARE
The foil making process
uses an environment-
friendly aqueous-solvent
technology that fully
complies with today’s green-product
design requirements. All terminations
are lead-free. Packing materials can
be recycled.

Telefonieaktiebolaget L M Ericsson,
