DESCRIPTION
This 2.45 GHz ceramic multilayer antenna has been
designed to meet the requirements of the Bluetooth
TM(1)
and IEEE 802.11b/g 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.
