SPE-12-8-079/B/RC Page 1 of 12 SPECIFICATION Part Number : ILA.01 Product Name : Low Profile and High Efficient 915 MHz ISM Band Loop Antenna Features : Small size antenna, low profile and high efficiency
915 MHz ISM Band
10x3.2x0.5mm size SMT Compatible RoHS Compliant
SPE-12-8-079/B/RC Page 2 of 12 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 antenna s. 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 a nd 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 monitor ing, healthcare, sensing and others. 2.

Allocate the antenna on the longest side of the board. Center the antenna at the edge of the board. The antenna must be at the limit of the ground plane on the selected edge. of the CPW ground to the keep out area of the antenna. Keep the matching circuit close to the antenna. Keep the “W” distance as the width of that GND pad. Keep the antenna 1 mm away from the enclosure. The CPW dimensions will change depending on PCB. the keep out area or antenna, at top and bottom layers. edge of the keep out area or antenna, at top and bottom layers.
