1. Introduction
The ILA.01 is a 915 MHz ISM band antenna with excellent efficiency, 60% at the center
frequency and 45% at the band edges. 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.01 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.01 is the ideal
choice. The ILA.01 Loop antenna can be used in automated meter reading (AMR), radio
frequency identification (RFID), remote monitoring, healthcare, sensing, and other 915 MHz
applications.
