As researchers around the world race toward the realization of 6G wireless communication systems, the need for antennas that can dynamically adapt to ever-changing signal environments has never been ...

Antenna design is often referred to as a black art or witchcraft, even by those experienced in the space. To that end, [Janne] wondered—could years of honed skill be replaced by bruteforcing the ...

Abstract: This letter presents a wideband directional borehole radar antenna designed for three-dimensional, high-resolution tunnel ahead geological prospecting. The design employs a sigmoid-profiled ...

Abstract: This work explores reconfigurable antenna arrays with controlled radiation patterns, widely used in modern wireless and radar systems. By dynamically adjusting the beam direction, such ...
