Confirmation of Zero-N Behavior in a High Gain Grid Structure at Millimeter-Wave Frequencies

Confirmation of Zero-N Behavior in a High Gain Grid Structure at Millimeter-Wave Frequencies

A multilayer grid structure that has been used previously to create an antenna with high directivity and gain and that has been explained as having a near zero index of refraction is extended to millimeter-wave frequencies. Alternate explanations for the associated phenomena are examined. Further co...

Zusammenfassung:A multilayer grid structure that has been used previously to create an antenna with high directivity and gain and that has been explained as having a near zero index of refraction is extended to millimeter-wave frequencies. Alternate explanations for the associated phenomena are examined. Further confirmation of this zero-n behavior is presented.
