“…A further key requirement is that these antennas are made efficient, so as to prolong battery life. This paper is an extension of work originally presented in the 2017 International Workshop on Antenna Technology in Athens, Greece [1]. The discourse on additively manufactured (AM) voluminous antennas is expanded to provide an overview of electrically small antennas (ESA) in literature fabricated using novel techniques, the three-dimensional (3D) powder bed fusion (PBF) printing process, the antenna design process, as well as the implications of simulated and measured results on practical antenna design.…”
