Abstract: A dual-band ultra-wide beam quadrifilar helical antenna (QHA) for satellite positioning is proposed. The branching method is used to realize the dual-band operation of the QHA. A section of ...

Abstract: This paper presents a numerical investigation of anti-reflection coating (ARC) effects on the beam performance of a spiral-fed half-hemispherical silicon lens antenna for terahertz (THz) ...

This modern spiral staircase is part of a city park structure in Shenzhen, China. With clean design and open space, it connects different public levels and serves as both a walkway and an ...

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 ...

Magnetic resonance imaging (MRI) is one of medicine's most powerful diagnostic tools. But certain tissues deep inside the ...

This tool is the newest addition to the AntennaXpert ecosystem, complementing Taoglas’ Antenna Builder and Cable Builder.

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 ...
