Abstract: Super-directive antenna arrays (SDAAs) suffer from low realized gain caused by high impedance mismatches and low radiation efficiencies. Additionally, since the maximum radiation is directed ...

Astronomers have recently been taken aback by the discovery of an object in space that seems to be defying the common laws of celestial movement by orbiting backwards. This surprising discovery, which ...

Abstract: A 45° slant polarized radar antenna is designed using gapwaveguide technology. Using slant polarization in radar antennas is beneficial for collision avoidance applications as interference ...
