Useing of double-positive and double-negative materials for minimisation of stratton-chu antenna size


J. A. Stratton and L. J. Chu were the first scientists who solved an antenna problem with radiation of a ring slot on a conducting sphere [1]. It was almost seventy years ago. There were some inconveniences in that solution. Firstly, the slot width was not taken into consideration so a reactive part of radiation admittance was not defined. Secondly, the… (More)
