A crane lowers the 112-foot-wide (34-meter-wide) steel framework for the Deep Space Station 23 (DSS-23) reflector dish into ...

it converts the divergent emission from a horn antenna (a common RF source) into a wave with planar wavefront—a highly directional beam. They also demonstrated that more complex wavefront ...

Among them, SSPP leaky-wave antennas possess flexible control, a wide frequency band and high gain and can realize large ...

Studies have shown that the efficiency of surface-wave-excited plasma monopole ... respond to electromagnetic fields. Beam Scanning: The ability of an antenna to change the direction of its ...

As the demand for high-speed wireless communication grows, millimeter-wave frequencies, such as the 27 GHz band, have become increasingly important for 5G and beyond. However, operating at these ...
