ISM SavviTM Ceramic Antennas
868MHz / 915MHz
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 handheld devices, media players
and other mobile devices.
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.

Greater Flexibility
Ethertronics’ first-in-class IMD technology enables you to develop concept
designs that are more advanced and that deliver superior performance in
reception critical applications.
KEY BENEFITS
Electrical Specifications
Typical Characteristics, on 40x100mm PCB,
frequency of operation depends on tuning
Stay-in-Tune
IMD antenna technology
provides superior RF field
containment, resulting in less
interaction with surrounding
components.
Quicker Time-to-Market
By optimizing antenna size,
performance and emissions,
customer and regulatory
specifications are more easily
met.
