ISM 868 & 915 MHz Embedded Ceramic Antenna 868 MHz; 915 MHz 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. APPLICATIONS * * * * Embedded design Cellular, Headsets, Tablets Gateway, Access Point Handheld 11/15/2018 * * * * * * Telematics Tracking Healthcare M2M, Industrial devices Smart Grid OBD-II 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.

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. Other Shorting pin Ethertronics Shorting pin and feed pin are shared in Ethertronics ceramic antennas Feed pin Antenna tuning loop: Figure 1 Typical Antenna Layout Figure 2 Ethertronics Antenna Layout (Required) * * (c) 2018 Ethertronics 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. tel +(1) 858.550.3820 | fax +(1) 858.550.3821 email: eth.info@avx.com 5501 Oberlin Drive, Suite 100 San Diego, CA 92121 - USA DATASHEET | Part No. M620720 ISM 868 & 915 MHz Embedded Ceramic Antenna Specifications Ethertronics produces a wide variety of standard and custom antennas to meet user needs.
