Abstract
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.
