UWB Transparent THz antenna for Medical Imaging and Satellite Communication Applications

Abstract

The mm-wave and terahertz (THz) biomedical imaging shows promising specification in some applications such as quality control, protein characterization, pharmaceutical and cancer detection using non-ionizing radiation. A new UWB transparent antenna with high performance has been designed on polyamide and tetra-ethylene as substrate and copper, gold and ITO as conductors. The proposed antenna has a broad BW from 0.96 THz to 20 THz along with a resonance at 0.6 THz. Furthermore, the antenna presents 6.13 dB maximum gain, 8.2 dBi maximum directivity, 87 % maximum radiation efficiency and reasonable stable radiation pattern throughout the frequency band.
