At submillimeter-wave frequencies, hollow metallic waveguides offer better performance in terms of losses compared to conventional planar transmission lines like the microstrip and coplanar waveguide transmission lines. This is especially important for applications where relatively long transmission lines are needed such as high efficiency, on wafer leaky wave antennas. For example, rectangular waveguide based, frequency scanning, leaky wave antennas at Y-band (~240 GHz) have been demonstrated in (A. Jam, K. Sarbandi, and M. Vahidpour, APSURSI 2014, 1371-1372, 2014) with efficiency in excess of 55%. Furthermore, a low temperature fabrication process is highly desirable for possible integration with other pre-fabricated components without sacrificing their performance.
