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.
