Sub-Millimeter Wave Frequency Scanning 8 X 1 Antenna Array
By
Progress In Electromagnetics Research, Vol. 132, 215-232, 2012
Abstract
In this work, a sub-millimeter wave frequency scanning 8 x 1 element antenna array is presented for its use in a terahertz imaging system operating in the 220-330 GHz frequency band. The antenna array is formed by eight open ended waveguides, a phase-shifting network implemented with WR-3 rectangular waveguides and a power divider. Dielectric rods are used to improve the radiation patterns at large beam-steering angles. Prototypes of antenna arrays with and without the dielectric rods have been manufactured and experimentally characterized. A beam-steering range greater than 40° has been obtained for a frequency sweep between 270 GHz and 330 GHz.
