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...

In this paper, the use of a three element solution is studied for Low-Power Wide Area Network (LP-WAN) communication from space. A compact size with RHCP and wide beam-width radiation pattern performance is desired. The three element structure is compared with a quadri-fillar solution in term of frequency bandwidth, radiation pattern beamwidth...
