Ethertronics’ series of Ceramic 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 Bluetooth
®
enabled cell phones, media players
and other mobile devices.
Ceramic Wi-Fi / Bluetooth
Antenna
2400 – 2485 MHz
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.
Electrical Specifications
Typical performance on 40 x 60 mm PCB
KEY BENEFITS
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.
Reliability
Products are the latest
RoHS version compliant.

Antenna Layout Tips (General reference)
Important, layout guidelines for correct operation of Ethertronics Ceramic Antennas. Please read guidelines below
before laying out the antenna in a device. Figure 1 shows the typical antenna layout. Figure 2 shows Ethertronics’
antenna layout.

•
The antenna tuning loop is formed by the
PCB layout.
The feed pin and shorting pin are
combined because it requires very close
proximity to achieve more band- width.
