GAP waveguides is a novel packaging technology for millimeter wave and terahertz circuits and components that has unique advantages compared to existing transmission line and waveguide technology.
The technology enables planar solutions with extremely low losses, operating typically from 30 GHz to THz in applications such as antenna systems for Gigabit speed wireless communication and backhaul.
The technology is based on an Artificial Magnetic Conductor that enables contactless propagation of electromagnetic waves, significantly reducing transmission losses.
Antennas based on the GAP technology have over 10 times lower losses than micro strip lines, over 3 times lower losses than SIW, and approximately the same losses as rectangular waveguides.
The GAP waveguide technology has unique possibilities of creating tightly integrated solutions, including planar antennas, filters, diplexers, and other active components. GAP antennas with multiple ports are suitable for beamforming applications.
The superior performances of the GAP waveguide technology, both as a transmission line for making advanced microwave circuits and as a packaging technology, have been verified and described in several scientific journal articles, letters, and conference papers.
