Background:

Reflectarrays offer a low-profile alternative to parabolic dishes for beamforming.
Achieving multi-band operation and desired bandgap characteristics in reflectarrays remains a challenge.
Dielectric reflectarrays are attractive for reduced losses compared to metallic counterparts.

Purpose of the Study:

To present a novel 3D-printed fully dielectric bi-material reflectarray.
To incorporate bandgap characteristics for multi-band applications using a 1D Bragg reflector unit cell.
To validate the performance of the proposed reflectarray through fabrication and measurement.

Main Methods:

Design of a 1D Bragg reflector unit cell with a spatially varying refractive index.
3D printing of a bi-material reflectarray with specific dimensions (121.5 mm × 121.5 mm) and f/D ratio of 0.5.
Measurement of reflection gain, aperture efficiency, and transmission coefficient.

Main Results:

The fabricated reflectarray demonstrated a measured gain of 27.22 dBi at 27 GHz, with an aperture efficiency of 35.05%.
Simulated and measured performances showed good agreement within the 26-30 GHz frequency range.
High transparency was confirmed, with a transmission coefficient of 0.32 dB at 39 GHz.

Conclusions:

The proposed 3D-printed dielectric reflectarray effectively utilizes a 1D Bragg reflector for bandgap control.
The design is suitable for multi-band frequency applications due to its tunable bandgap characteristics.
The achieved gain, efficiency, and transparency highlight the potential of this technology for advanced RF systems.
