1. INTRODUCTION
The ILA.01 has excellent stability and sensitivity to consistently provide high signal reception
efficiency, 60% at centre frequency and 45% 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 antennas. The antenna at 10x3.2x0.5 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 in devices where
orientation of the product is unknown. The ILA.01 Loop antenna can be used in automated
meter reading, (AMR), radio frequency identification (RFID), remote monitoring, healthcare,
sensing and others.
