Latest Patents
Stephen Essman holds a patent for a tapered anechoic chamber. This invention includes tapered anechoic chambers and chamber systems, as well as machines or electronic apparatus utilizing these aspects. The patent outlines methods and processes for using these devices and systems. A notable feature of his design is the use of a TEM antenna, which is terminated by a resistive card, or R-card. This configuration allows for a broadband antenna that effectively illuminates the test zone without the need to change the feed antenna.
The preferred chamber design incorporates a Chebyshev absorber layout, which is a novel approach for tapered chambers. This layout positions wedge absorber tips and pyramidal absorber tips at varying heights, optimizing wave reflections and minimizing stray signals in the test zone. Additionally, the design allows for easy adjustment of polarization from vertical to horizontal by rotating the feed structure, enhancing usability without disconnecting cables.
