Specification Part No. : ISA.05.A.033822 Product Name : 915 MHz ISM Band Adhesive Mounted Patch Antenna for Internal Applications Features : Double-Sided 3M Adhesive Mounted Antenna 5dBi Peak Gain mounted on 30cm Square Ground 0dBi Peak Gain In Free Space Dimensions: 80x50.5x11 mm 300 mm Φ1.37 cable IPEX MHFHT connector (U.FL compatible) IP65 water-proof Cable and connector customizable RoHS Compliant SPE-15-8-036/B/WY Page 1 of 16 1. Introduction The Taoglas ISA.05 adhesive mounted antenna is designed primarily for 915 MHz ISM Band compact wireless applications where it may or may not be attached to metal. When placed on a reference 30cm square ground-plane, the antenna has an excellent directional hemispherical radiation pattern, high peak gain of 5dBi at zenith, and an efficiency of 68%. Even without a ground-plane underneath, the antenna achieves 0dBi and an efficiency of 45%. The antenna is IP65 water-resistant and comes standard with a Micro-Coaxial cable with 1.37mm diameter and IPEX MHFHT connector. The Taoglas ISA.05 is an excellent solution for the following applications: - Environments where there are lots of metal objects that it may be mounted to (such as near a car engine) - RFID Readers - Short range 915MHz mesh networks Cable type, length, and connector can be customized. Mechanical customization of the antenna can also be done for a minimum order quantity. Please contact your regional Taoglas office for more details. SPE-15-8-036/B/WY Page 2 of 16 2.
