Fully metallic geodesic lens antennas are popular for millimetre-wave band applications due to their simplicity, robustness and low loss. Here, we report the experimental results of a array antenna, which was specifically designed be additive-manufactured in one single piece using Laser Powder-Bed Fusion (LPBF). LPBF aluminum alloy AlSi10Mg is able produce high conductivity relatively surface r...

After the Federal Communication Commission (FCC)’s authorization of frequency band of 3.1 to 10.6 GHz for unlicensed radio applications, ultra-wideband (UWB) technology be‐ come the most promising candidate for a wide range of applications that will provide signif‐ icant benefits for public safety, business and consumers, and attracted a lot attention both in industry and academia. The antennas...

In order to improve measurement efficiency in electromagnetic test facilities (compact range or near-field range), testing probes are required to have ultra-wideband (UWB) radiation characteristics, dual-polarization capability, and interchangeable Eand H-plane farfield patterns. In this context, we propose a new type of UWB antenna that satisfies these requirements in the frequency range of 4 ...

Here, we propose a low-profile polarizing technique integrated in parallel plate waveguide (PPW) configuration, compatible with fully metallic geodesic lens antennas. The shape of the antenna is chosen to resemble operation Luneburg lens. fed 11 ports 10° separation producing switchable beams an angular range <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www...
