Herein, design and manufacturing of an X-band pyramid horn antenna using 3-D printer is studied with its experimental results. X-band is used for the military purposes with the marine and satellite technology based on the geographic discovery. Horn antennas are especially very preferable in these applications since they can be built easily at the different types depending on their utilizations and...
This paper presents pyramidal horn antennas operating at 28 GHz, which are manufactured by 3D printing technology. A printed antenna based on a WR-28 waveguide standard gain horn designed for 20 dBi gain is then metalized using two different methods. Copper tape and conductive copper paint are applied to the 3D printed geometry surface. A full-wave electromagnetic simulator, HFSS, is used to design...
In this paper we present the design of an antenna, operating in the Ku-band, conceived for wireless power transfer systems. It comprises an hemispherical dielectric lens, fabricated using 3D printing technology, fed by a microstrip patch antenna array. The conjugation of the dielectric lens with the microstrip patch array allows the development of a compact high gain antenna. The antenna presents...
This paper presents three low cost 3D printed antenna concepts for integration with a miniature mm-wave platform. The proposed solutions are optimized to operate in mm-wave ISM band (122GHz-123GHz). Different, inexpensive, detachable antennas can be used with the same platform for various RF sensing applications such as food safety, health and industrial.
A near isotropic 3D printed antenna on a cubic structure is presented in this work for the first time. The fully inkjet printed antenna has been realized by a unique combination of 3D inkjet printing of dielectric and 2D inkjet printing of metal. The antenna comprises a 1.5λ0 dipole that is wrapped around the cube to achieve a near isotropic radiation pattern. The cube measures 2 cm × 2 cm × 2 cm,...
In this paper, a substrate integrated conformal antenna based on a 3D-printing conical pedestal is demonstrated. This array is mounted on a cone with a radius on the top of 15 mm and a radius on the bottom of 35 mm. It is synthesized at the center frequency of 35 GHz. It is not an easy task to fabricate a non-planar structure, thus the 3D printing technology is used to fabricate the cone. This method...
A method to measure an antenna's performance when mounted to an electrically large and complex-shaped spacecraft is described. In the past, either time-intensive numerical simulations or antenna range measurements of an expensive full-scale model of the spacecraft were used to determine the antenna's performance. An alternative method fabricated a reduced-size scaled spacecraft model using 3-D printing...
Low cost 3D printed monopole fluid antenna is investigated. The PDMS container of the seawater is fabricated by 3D printing technology for reducing cost and complexity. The design parameters of the antenna have been studied for efficiency improvement. The achieved peak efficiency is about 70% at 2.75 GHz, and the impedance bandwidth is about 67%. Stable radiation patterns are demonstrated across the...
This paper investigates the capabilities of additive manufacturing techniques for building RF antennas in the Ku-band frequency range. Two different compact medium to high-gain antennas, a ring-focus dual-reflector antenna and a spline-profiled smooth horn antenna, were designed, built and tested for this purpose. The antennas were manufactured using the latest 3D printing techniques, i.e. based on...
In this paper, we present a 3D passive UHF RFID tag that is fabricated utilizing direct write printing method. The dual antennas tag is printed using the dispensing technique on a wooden cube with dimension of 8 cm3 (2 cm × 2 cm × 2 cm), which is the smallest RFID tag fabricated in 3D structure so far. The narrow-line tag antenna has a near-isotropic radiation pattern which enabling the tag with full...
An ultra-wideband (UWB) monopole antenna on an additive manufactured (AM) flexible substrate for foot wear application is proposed. The 3D printing of foot phantoms for the testing of this type of antennas is also introduced. Inexpensive fuse filament fabrication (FFF) technology is utilized for these developments. Flexible polylactic acid plastic filament (PLA) material is used for the antenna while...
A technique for designing a parasitic patch antenna array whose beam can be steered dynamically using a fluidic tuning mechanism is presented. Using this technique, a three-element patch antenna array operating at 5 GHz is designed and fabricated using 3D printing. Two oil-filled channels are placed in the substrate of the antenna along the radiating edges of the patches and filled with movable metal...
