“…Expensive processes, such as diffusion bonding, are employed to achieve the required fabrication accuracy at D-band. Dielectric lens antennas [3]- [5] are the preferred option to ensure high gain over wide frequency ranges. However, being oversized and non-planar, they are unsuited for ultra-dense deployment and tend to exhibit reduced radiation efficiency for very high gain values [5].…”

We present novel three-layer D-band linearly-polarized transmitarrays entirely fabricated using standard printed circuit board (PCB) processes. Three flat lenses comprising 1600 elements are designed to generate broadside and scanned beams. All lenses are synthesized using 8 unit cells (3-bit phase quantization). The combination of cells comprising probe-fed and aperture-coupled patches is proposed to overcome the design challenges due to technological constraints and achieve a wideband operation. The minimum design feature is 80 µm. The trade-offs in the design of the feed illumination are analyzed using adhoc numerical tools. A 10-dBi horn is eventually selected as source. The focal-to-diameter (F/D) ratio is 0.75 for all lenses. The broadside array attains a peak gain of 33.0 dBi and a -1-dB relative gain bandwidth of 11.7%, i.e. wider than that of state-of-the-art designs, in the 100-300-GHz band, which use more complex technologies and larger focal distances. The performance of the proposed antenna technology demonstrates its potential for low-cost high-capacity wireless backhauls beyond 100 GHz.
