“…Waveguide is dispersive, so shorter feed sections can be used for substantial phase shifts. However, microstrip quasi-TEM feeds have also been implemented, e.g., in an 18 elements L-band phased array with 100 steering [15]. A microstrip array with Fig.…”

This paper describes frequency scanning slot arrays operating from 130 to 180 GHz. The arrays are micro-fabricated using the PolyStrata sequential copper deposition process. Measured reflection coefficient and radiation patterns agree with HFSS full-wave simulations. The voltage standing wave ratio is less than 1.75:1 over the entire frequency range, and the measured scanning is 1.04 GHz from 130 to 150 GHz and 32.5 over the full frequency range. The measured gain is 15.5 dBi for a 10-element array at 150 GHz and 18.9 dBi for a 20-element array at 150 GHz with about 3 dB of variation over the scan range.Index Terms-Beam steering, g-band, linear antenna arrays, millimeter wave radar.
