In this paper, we present the design, fabrication, and measurement of an ultra-wideband phased array antenna, with continuous coverage of all six allocated fifth generation and industrial, scientific, medical bands in the millimeter-wave spectrum. Of importance is that the complete array is co-fabricated as a single printed circuit board using commercial processes, implying a significant reduction in cost over previous microfabrication-based designs. The design is demonstrated in simulation to operate across 24-72 GHz with VSWR<;2.2 at broadside and VSWR<;3 for ±45° scanning in all planes. These simulations are validated through the fabrication and measurement of a 3 × 3 array prototype, which shows close agreement to the simulated values.
