“…These advantages make it a promising candidate for THz communication systems [13]. For many years, corrugated horn antennas have been examined as antenna feeds, and due to technological development, it has become possible to fabricate [14,15]. Outer space missions require high-quality factor subsystems.…”

Technological advancements have revolutionized the space industry, facilitating deep space exploration using CubeSats. One objective is to locate potential life-support elements, such as water, on extraterrestrial planets. Water possesses a distinct spectral signature at 183 GHz, useful in remote sensing and environmental monitoring applications. Detecting this signature provides crucial information about water and ice presence and distribution on celestial bodies, aiding future exploration and colonization efforts. Mostly in space remote sensing uses corrugated horn antennae due to high gain and radiation patterns but fabrication of corrugated antenna is very challenging or even impossible in some cases. To ease this challenge, in our research we propose ideas to transform a corrugated horn antenna into a smooth-walled design by using MATLAB Cubic smoothing Splines algorithms. We compare simulation results between smooth-walled and corrugated antennas, and we can see some improvements in insertion losses, Voltage Standing Wave ratio (VSWR), and gain. We also manufactured this 183 GHz antenna using a commercially available 3D printer by utilizing Acrylonitrile Butadiene Styrene (ABS) material. The antenna surface was then coated with a thin layer of copper using conductive paint. In the end, we practically evaluate smooth-walled antenna functionality and compare it with the theriacal results. Validating the antenna’s functionality proposes a cost-effective and accessible production method to be used in a CubeSat engineering model or university students’ project.

“…The similar concepts of increasing the gain through two plates of five bowtie metallic elements has been proposed in the corrugated SIW horn antenna. 11 Various types of dielectric loading have been proposed in References 12 and 13 to improve the gain of H-plane sectoral SIW horn antenna. The proposed design of 14 placing the diamond shaped metallic patch at both the side of SIW horn antenna also improves the impedance matching and hence high gain had been achieved.…”

A low-profile three-dimensional substrate integrated waveguide (SIW) horn antenna array with its novel feeding structure is proposed in this article. The feeding element is capable of transforming the wave from one plane to its orthogonal plane. Such type of three-dimensional SIW, H-plane horn antenna design is not available in the existing literature. The design is proposed to provide high gain for radar, 5G, and satellite communication applications. The single SIW horn antenna does not have significant gain at the desired frequencies. When the antenna element is loaded with dielectric the gain improves by 1.4 dB. The antenna elements are further arranged in a box shape, forming a three-dimensional array, which improves the gain significantly. Such structure shows dual band characteristics and provides gain of 11.3 dB at 28.26 GHz and 9.64 dB at 29.41 GHz. The same three-dimensional design when loaded with dielectric at the aperture end also show a dual band behavior and improve the gain further to 12.5 dB at 28.12 GHz and 12.55 dB at 29.28 GHz. The proposed three-dimensional antenna designs are compared to four element linear array designs, and it shows substantial improvement in gain for the desired frequency.
