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 
IMDs 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 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 ISM enabled M2M, tracking and smart metering 
applications.
