This paper presents a slot array antenna composed of H-plane horns as radiating slots and a pillbox feeding mechanism in gap waveguide (GW) technology.This new configuration presents a new full-metal slot array antenna with low complexity, fabrication cost, and high gain and directive radiation.The proposed fully metallic antenna leverages a design that offers high efficiency and a flat gain response over the desired bandwidth.A fabricated prototype exhibits 70–90% efficiency, an impedance bandwidth of about 8% (S11 < -10 dB), and a 2.5 dB gain variation across the operating bandwidth..
Five Takeaways From Trump's Plans To Build an Iron Dome for America
This is a game-changer in the New Cold War since it’ll take the US’ rivalry with Russia and China to a qualitatively more dangerous level through the consequent hyper-militarization of space. Trump signed an Executive Order to build an Iron Dome for America, which aims to defend the homeland “against […]
