SPE-12-8-080/C/RC Page 2 of 12 1. Introduction The ILA.02 is a 868 MHz ISM band antenna featuring an excellent efficiency of 60% across the band. This antenna works the best when placed at the center of the board edge. The antenna, at 10 x 3.2 x 0.5 mm, is low profile and would be suitable for devices wi th space constraints. The ILA.02 is delivered on tape and reel and now allows M2M customers to use an omni-directional SMT antenna . The omni -directional rad iation 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.02 is the ideal choice. The ILA.02 Loop antenna can be used in automated meter reading (AMR), radio frequency identification (RFID), remote monitoring, healthcare, sensing, and other 868 MHz applications. 2.
