An ultra‐wideband 3D‐printed dielectric reflectarray antenna (DRA) is proposed in this letter. The dielectric reflectarray unit (DRU) adopts the photosensitive resin therm1220, which dielectric constant of 3.97 is conducive to improving the bandwidth. Through adjusting the size of the DRU, the reflection phase can be adjusted. The dielectric reflectarray is 23 × 23 element which printed by stereo lithography apparatus (SLA) and is realized by installing a metal plate with four resin screws. The measured of the gain covers 25.8–28.9 dBi from 27.5 to 38 GHz. And the 3‐dB gain bandwidth of measured is 32.1%. The measured aperture efficiency is basically above 30% from 28 to 35 GHz. The maximum gain is 28.1 dBi at 30 GHz, and the aperture efficiency is 39% during measurement. The 3 dB beam width of the E‐plane and H‐plane are both about 5.4° in Ka‐band. A good agreement can be observed between measurement and simulation.

“…As can be observed, benefits include structure size and dual-band functionality (in the L-and S-band). The existing works [1,17] reported the CP antennas with high gains, but the physical dimensions of the antenna arrays are relatively high. There is a trade-off between the array profile and the gain.…”

“…In addition, powders with negligible to high electrical conductivity (i.e. similar to dielectrics and copper or aluminum), can be used to print dielectric [1,2] and metallic-based antenna structures [3][4][5], respectively. Following this trend, there have been a number of 3-D printed satellite antennas reported [9,10] constituted mainly by dielectric resins, and this research is important as such antennas are needed to support current and future 5G/6G wireless communications and satellite systems [11,12].…”

This letter presents a three‐dimensional (3‐D) printed metallic antenna array that combines folded‐shorted patches (FSPs) and meandering for structure compactness. The design provides dual‐band functionality, operating in the L‐band and the S‐band. The compact and broadband feeding network, which is also integrated onto the backside of the antenna ground plane, enables circularly polarised radiation over an operational bandwidth of more than 80%. The dimensions of the array are 0.4 × 0.4 × 0.056 (where λ0 is the free space wavelength at 1.2 GHz), making the design suitable for CubeSats and other space constraint applications. The measured right‐handed circular polarised realised gains are 2.32 dBic and 1.84 dBic at 1.2 GHz and 2.45 GHz, respectively. In addition, the 3‐D metallic printed FSP elements can be flexibly arranged for different link requirements and other applications like beam steering.
