Bluetooth Antennas
2.4—2.5 GHz
KEY BENEFITS
DESIGN ADVANTAGES
Best in Class Performance—Smallest Occupied Volume
•
Powerful combination of 81% peak efficiency and
simple implementation guidelines.
•
Minimal ground clearance and component “keep out”
areas. Very low component height.
•
High selectivity eliminates the cost for additional
filters and frees up board space
High Tolerance to Frequency Shifts
•
IMD’s high RF isolation resists antenna detuning that
otherwise can impair reception.
•
Single part works for various PCB sizes and layouts.
Quicker Time-to-Market
•
Fewer design modifications required to pass RF
test suite.
•
Simpler implementation—no
matching networks.
RoHS Compliant
•
Antennas comply with appropriate RoHS Directives.
Ethertronics’ Savvi series of Isolated Magnetic
Dipole™ (IMD) antennas deliver on the key needs of
device designers for higher functionality and
performance in smaller/thinner designs. These
innovative antennas provide compelling advantages
for Bluetooth enabled cell phones, media players and
other mobile devices.
TECHNOLOGY ADVANTAGES
Real-World Performance and Implementation
Ceramic antennas may look alike on the outside, but
the important difference is inside. Other antennas
may contain simple PiFA or monopole designs that
interact with their surroundings, complicating layout
or changing performance with use position.
Ethertronics’ antennas utilize patented IMD
technology to deliver a unique size and performance
combination.
Stays in Tune
High RF isolation means
IMD antennas resist de-
tuning regardless of
usage position. And
one standardized part
can typically be placed
in a variety of locations.
Smallest Effective Size
IMD antennas require a
smaller keep-out area for surrounding components,
leading to a smaller effective size.
High Performance
IMD’s high efficiency and simple design rules lower
development risk and speed time-to-market without
sacrificing performance. Plus, high RF selectivity
eliminates the cost and space for band-pass circuitry.

END USER ADVANTAGES
Superior Range
•
Greater antenna efficiency means longer range and
a better end user experience.
Exceptional Coverage
•
Better coverage delivers more reliable wireless
connections for mobile phones, laptops, stereo
headsets, cars, media players, audio systems
and more.
SERVICE AND SUPPORT
Extensive RF Experience
•
Our Savvi ceramic antennas are supported by exten-
sive application notes, and when needed, by the
expertise of RF engineers who have integrated
hundreds of antenna designs into wireless devices.
Global Operations & Design Support
•
Ethertronics’ global operations encompass an
integrated network of design centers that provide
local customer support.
