Their cariations were experimentally r;erifred by analyzing u set of newly designed untennu elements with substrates satishirig the criteria h 5 Q.V81SA,, for 2.22 5 E~ 2 10.2, where A, is the free-space wauelength, h the thickness, and E, the relative permittiiiiy ofthe dielectric substrate. 0 l Y Y 6 John Wiley & Sons, Inc.

However, steeples of tuning is little at closer distances between the ring and anode block. The reason of this phenomena is arising of capacitive component of conductance carry in with ring to circuit. Because it moves resonant frequency to opposite direction, the summary variety on little distances is too little, and in some cases the frequency starts to move in the opposite direction. The same circumstance can lead to a narrowing of the tuning range by ring eccentricity.

He has produced empirical antenna designs (Vee dipoles) similar to those discussed in this article. We would like to thank him for sharing with us his insight into this problem. Also, we would like to thank Dr. Karl Steinbach of the U.S. Army, European Research Office for his helpful comments.
