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.

Ethertronics’ global operations encompass an
integrated network of design centers that provide
local customer support.
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.
DESIGN ADVANTAGES
Best in Class Performance—Smallest Occupied Volume
Powerful combination of 63% peak efficiency and sim-
ple 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 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 implementationno matching networks.
RoHS Compliant
Ethertronics’ antennas comply with the European RoHS
Directive 2002/95/EC.
