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.
