1. INTRODUCTION
The ILA.02 has excellent stability and sensitivity to consistently provide high signal reception
efficiency, 60% at centre frequency and 60% at the edges. Based on the loop effect this antenna
works the best when placed on the centre of the edge of the board, working better than
traditional linear polarized chip antenna. The antenna at 10x3.2x0.5mm 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 in devices where orientation of
the product is unknown. The ILA.02 Loop antenna can be used in automated meter reading,
(AMR), radio frequency identification (RFID), remote monitoring, healthcare, sensing and others.
