1. Introduction 1. Introduction 1. Introduction 1. Introduction 1. 1. Introduction FXP.89.A is a narrow-band ISM flex antenna for devices requiring an antenna potted in an epoxy substrate. The antenna can be lumped-element matched for center frequencies ranging from 784 MHz to 915MHz. FXP.89.A is optimized for application in Pivot International’s “Rooster” tracking node device, and requires potting in URC E-Cast F-82 resin with hardener 118.
