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 with 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 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.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.
