Abstract: This article presents a dual-band dual-mode antenna with omni-directional radiation pattern in the lower band (LB) and reconfigurable pattern in the upper band (UB) for wireless body area ...

“The new platform—dubbed “charge programmed multi-material 3D printing (CPD)—is a universal system for rapid production of nearly all 3D antenna systems. It can pattern highly conductive metals with a ...

Abstract: In this chapter, 3D-printed microwave antenna is surveyed ... Several parameters of the printed horn antenna, such as return loss, radiation pattern, gain, and polarization, were analyzed ...

A 3D printing method creates antennas by combining metals and polymers, enabling designs and applications, including use in extreme environments. A 3D fractal tree antenna fabricated using charge ...

Add a description, image, and links to the antenna-pattern topic page so that developers can more easily learn about it.

Scientists from IISc and RRI have developed a novel 'fantail' antenna design capable of detecting faint signals in cosmic microwave background radiation (CMB) with unprecedented precision.

From budget enthusiast builds to pro setups, these are our picks of the most reliable 3D printers you can buy. James has been writing about technology for years but has loved it since the early 90s.

This monograph contains tables of the horizontal radiation pattern (h.r.p.) of a dipole mounted on a cylindrical mast. The table were calculated on a digital computer and this enabled a ...
