TECHNOLOGY ADVANTAGES 
KEY BENEFITS 
Part No. M830110  
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     
component 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      
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 
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.
