Abstract :
This paper introduces a new class of antennas, called self-structuring antennas (SSAs). An SSA has the ability to alter its electrical shape in response to changes in its environment. This property makes an SSA suitable for use in a number of traditionally difficult antenna situations. The basic principles of the SSA are introduced, and a number of potential applications are highlighted. Details of a simple prototype antenna are provided. Computer tools capable of analyzing the SSA are described, and results of both numerical and experimental investigations of the SSA are presented
