Abstract :
A comprehensive analysis of the radiation properties of an electrically small folded ellipsoidal helix antenna (EHA) is presented, showing its ability to self-resonate and impedance match without external components. Three antennas with different sizes and geometries have been designed to work at the 2.4-GHz ISM band and are realized using a selective laser sintering (SLS)-based fabrication process. The benefits of using this antenna for various size-restricted applications such as medical implants are also described.
