Description

This paper discusses the sub-GHz antenna design using for the communication between the terrestrial Internet of Things (IoT) to Low-Earth Orbit (LEO) satellites. In the first part, we will focus on the LEO constraints and the antenna characteristics that are suitable for this application. Then, first results using a compact tri-fillar configuration are presented with in-field testing and the EIRP limits. In the second part, a new solution to improve the radiation characteristics is proposed and analyzed.
