Gap Waveguide Technology Advantages
• Low loss (most of the designs are fully metallic)
• No need of electric contact
• Adaptability to plane surfaces
• Lower manufacturing cost
Circular polarization (CP) in wireless communications systems
has several advantages over linear polarization: CP does not
require polarization alignment between the transmitter and the
receiver and is more robust against multipath effects.
Why use Circular Polarization?
