DESCRIPTION
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.
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.
