Bluetooth™ Crispus Snap-In Antenna
Flexible low-profile design for
rapid assembly on PCBs
This is one of our standard Snap-In Antennas intended for use with all 2.4 GHz
applications where very high performance is combined with low profile snap-in
assembly directly on the printed circuit board. This half-wave antenna is inde-
pendent of ground plane to ensure stable performance.
The environment around the antenna will influence the antenna impedance.
In order to ensure 50 ohm impedance it is necessary to match the antenna
with external components for each particular application.
It is important to note that, upon request, this standard concept can be
customized according to your design.
Typical application areas are:
• Laptop PCs
• Desktop PCs
• Printers
• Instruments
• Network access points
Description
The Bluetooth Snap-In Antenna is a half-wave ( 2) antenna of compact design
intended for automated assembly (DFA) directly on the PCB without soldering.
The antenna easily snaps into place on PCBs.
