ABSTRACT:
Techniques, apparatus and systems that use composite left and right handed (CRLH) metamaterial structures to combine and divide electromagnetic signals at multiple frequencies. The metamaterial properties permit significant size reduction over a conventional N-way radial power combiner or divider. Dual-band serial power combiners and dividers and single-band and dual-band radial power combiners and dividers are described.
