Two designs of high gain dielectric lens for a V-band backhaul antenna, compatible with 3D printing, are compared. The available printing materials still have significant losses, which limit the performance of traditional focusing dielectric lenses, as the dome elliptical lens. Herein, we show that an all-dielectric transmit array can present several mechanical and electrical advantages, especially...
We present in this paper a cost-effective, high-gain V-band lens antenna system. The lens is illuminated by a planar antenna integrated on standard FR4 PCB along with a built-in connector using a fin-line microstrip-to-waveguide transition (enabling WR15 waveguide connection). The lens has an elliptical dome-type design destined to be manufactured in ABS plastic using 3D printing. The proposed antenna...
The use of 3D-printing based on extrusion depositing technologies for electromagnetic applications (such as dielectric antenna design or human mimicking tissues) is increasing as a low cost alternative to other small-scale fabrication technologies. As a result, it is of utmost scientific interest to know the exact dielectric properties of commercially available printable materials, such as polylactide...
The rapid growth of wireless data drives the development of new wireless technologies. We can have here in mind the current works on 5G standardization, wireless backhaul development in V/E Band, as well as low orbit mobile satellite service development in Ku band. For all those systems, the availability of high performance and cost effective antenna is key. To address this need, fundamental enablers...
In this paper, we investigate the performance of a 3D-printed plastic lens operating in the 120 GHz frequency band. An Integrated Passive Device module with built-in linearly polarized patch antenna is used as the source of the lens. The profile of the lens is based on elliptical shape. It is first optimized with Geometrical Optics (GO) and Physical Optics (PO) methods. Then, full-wave simulations...
During the past years, various research teams developed 60 GHz chipset solutions, using both advanced CMOS [1] and BiCMOS [2] technologies. But for the 60 GHz market to flourish not only low cost RFICs are required, low cost antennas and packages are also key elements. Recently, low cost High Density Interconnect (HDI) organic technology has been evaluated [3, 4] to develop 60 GHz module using antenna-in-package...
