KEY BENEFITS
DESIGN ADVANTAGES
Ethertronics’ Prestta series of Isolated Magnetic Dipole™ (IMD) stamped metal antennas address the
challenges facing today’s product designers. IMD’s
high performance and isolation characteristics offer
better connectivity and minimal interference.
IMD antennas can be used in a variety of devices:
• Access Points, Gateways, Routers
• Industrial Handhelds
• WiFi enabled Televisions & Monitors
TECHNOLOGY ADVANTAGES
Stays in Tune
IMD antenna technology
provides superior RF field
containment, resulting in
less interaction with
surrounding components.
Ethertronics IMD antennas
resist de-tuning;
providing a robust radio
link regardless of the
usage position.
Prestta WLAN antennas use patented IMD technology
in a stamped metal configuration to provide high
performance. IMD antennas requires a smaller design
keep-out area, carry lower program development risk
which yields a quicker time-to-market, without
sacrificing RF performance.
Quicker Time-to-Market
• By optimizing antenna size, performance and emissions, customer and regulatory specifications are more
easily met.
Greater Flexibility
• Ethertronics’ first-in-class IMD technology enables you
to develop concept designs that are more advanced
and that deliver superior performance in receptioncritical applications.
RoHS Compliant
• Ethertronics’ antennas are fully compliant with the
European RoHS Directive 2002/95/EC.
END USER ADVANTAGES
Unique Form Factors Support Advanced
Industrial Designs
• Smaller, more efficient IMD embedded antennas break
through restrictive design rules and provide new freedom in component placement.
Superior Range & Signal Strength
• Better antenna function means longer range and
greater sensitivity to critically precise signals—
delivering greater customer satisfaction while building
brand loyalty.
SERVICE AND SUPPORT
Extensive RF Experience
• Our WLAN antennas are supported by documentation,
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 supports an integrated
network of design centers that can take projects from
concept to production.
