The ILA.08 is a new 868MHz ISM band embedded ceramic loop antenna from Taoglas featuring a strong efficiency of 45% at the center of the band. It is the perfect solution for the growing amount of devices using the 868MHz band, such as Sigfox or LoRa applications in Europe, or in metering applications. Introduction This antenna works the best when placed at the center of the board edge. The ILA.08 antenna, at 5*3*0.5 mm, is low profile and would be suitable for devices with space constraints. The ILA.08 is delivered on tape and reel and now allows M2M customers to use an omnidirectional SMT antenna. The omnidirectional radiation characteristics allow for excellent performance regardless of device orientation. This is especially useful for devices that are not fixed in one particular spot during use. When there is little PCB space available for antenna placement, but high performance is required, the ILA.08 is the ideal choice. Introduction Introduction The antenna is manufactured in a TS16949 first tier automotive approved facility and has passed the most stringent reliability testing. Since it is SMD, it is much easier to integrate and more reliable in high volume production compared to helical antennas which are cumbersome to install and subject to variability due to the need for manual assembly. Introduction This antenna can be mounted with no performance degradation in either orientation as long as the antenna is soldered correctly via Surface mounting. Please see the integration instructions section for further detail regarding the optimum way to integrate this antenna into your device. For further optimization to customer-specific device environments and for support to integrate and test this antennas performance in your device, contact your regional Taoglas Customer Services Team.

A pi-matching network like the one shown below is required incase adjustments need to be made. The antenna EVB has the same matching network. The components on the EVB are a good starting point for a new design, but will need to be adjusted upon integration for best performance. The zero ohm resistor is needed to solder down a coax pigtail to make measurements with a vector network analyzer. SPE-16-8-050-B www.taoglas.com 10 6. Mechanical Drawing – Evaluation Board 6.
