TM
Embedded Ceramic
GPS & Bluetooth
®
Antenna
1.575 and 2.4—2.5 GHz
KEY BENEFITS
DESIGN ADVANTAGES
Best in Class Performance—Smallest Occupied Volume
•
High efficiency
•
Minimal ground clearance and component “keep out”
areas. Very low component height.
•
High selectivity eliminates the need for additional
filters and frees board space.
High Tolerance to Frequency Shifts
•
IMD’s high RF isolation resists antenna de-tuning that
can otherwise impair reception.
•
Single part works for various PCB sizes and layouts.
Quicker Time-to-Market
•
Fewer design changes
•
Simpler implementation—no
matching networks.
RoHS Compliant
•
Ethertronics’ antennas comply with the European RoHS
Directive 2002/95/EC.
These highly innovative antennas provide
competitive advantages for designers of cell phones,
laptops and other mobile equipment by combining
GPS & Bluetooth antennas in a single, highly compact
form factor suitable for the thinnest/smallest
devices. Ethertronics Isolated Magnetic Dipole (IMD)
technology utilizes superior RF isolation to deliver
the utmost in high performance.
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 technolo-
gy to deliver a unique size and performance combi-
nation.
Stays in Tune
High RF isolation means
IMD antennas resist
detuning 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.
Exceptional Coverage
•
Better GPS coverage delivers improved performance
in buildings, cars or other areas where signal
reflection occurs.
•
Better Bluetooth coverage means more reliable
wireless connections.
Faster Acquisition Times
•
Users experience faster signal acquisition for GPS
readings and Bluetooth connections.
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.
