ABSTRACT:
An antenna system is described having a plurality of elements, one of which is an active element for transmitting or receiving signal, the remaining lements acting as reflectors, and wherein the elements may be comprised of a series of diodes connected in series with conductors having a length that is a fraction of the wavelength of the design frequency. When its diodes are biased for conduction, an element can radiate or receive r.f. signals or act as a reflector, and when its diodes are not conducting, the element is transparent to r.f. of the design frequency.
