Datasheet
**DATASHEET** Part No. M310220 Product: Wi-Fi/ Bluetooth S-Band Ceramic Antenna
KYOCERA AVX's 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. Also covers S-Band for Satellite IoT applications.
## **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. KYOCERA AVX's’ antennas utilize patented IMD technology to deliver a unique size and performance combination.
## **Greater Flexibility**
KYOCERA AVX's 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.
## **Environmental Compliance**
Products are the latest RoHS version compliant.
## **APPLICATIONS**
- Embedded • Healthcare design (FDA Class I)
- • Headsets, • M2M, Industrial Tablets devices
- • Gateway, • Smart Grid Access Point • OBD-II
- • Handheld • Satellite IoT
- Telematics
