[PO] 3-D printing method advances electrically small antenna design

While most electronic components benefit from decreased size, antennas -- whether in a cell phone or on an aircraft -- suffer limitations in gain, efficiency, system range, and bandwidth when their size is reduced below a quarter-wavelength.

"Recent attention has been directed toward producing antennas by screen-printing, inkjet printing, and liquid metal-filled microfluidics in simple motifs, such as dipoles and loops," explained Jennifer T. Bernhard, a professor of electrical and computer engineering at the University of Illinois at Urbana-Champaign. "However, these fabrication techniques are limited in both spatial resolution and dimensionality, yielding planar antennas that occupy a large area relative to the achieved performance."

"Omnidirectional printing of metallic nanoparticle inks offers an attractive alternative for meeting the demanding form factors of 3D electrically small antennas (ESAs)," stated Jennifer A. Lewis, the Hans Thurnauer Professor of Materials Science and Engineering and director of the Frederick Seitz Materials Research Laboratory at Illinois.

Nice innovation, wonder how long before we see it in production?

Does anyone have an idea what this tech will be implemented in?
