Design and Characterization of a Traveling-Wave Antenna for Millimeter Applications in the Sub-THz Band
Résumé
The main challenge in manufacturing antennas in the sub-THz band is their small size, which requires adapted manufacturing tools. Tis paper proposes a uniform linear 3 × 1 traveling-wave antenna array (ULTWAA) for millimetre applications in the sub-THz band. Te designed array allows a continuous beam orientation of ±46.1° in the E-plane. A small quarter-wave line added to the ends of the antenna allows the beam to be oriented towards the inside of the antenna, cancelling out surface waves and adapting the impedance to the scanning angle. Tanks to this device, the waves produced are progressive. Te antenna manufactured at 100 GHz measures 13 × 9.7 × 0.125 mm. Te measured peak gain is 14.2 dBi with 70% bandwidth. For in-phase radiation, the distances between the antenna units have been adjusted, but the adjustment process is tedious due to the interdependence between the antenna units.
