Abstract

Abstract : A new family of waveguide power splitters based on the use of connected bi‐omega particles is presented. The new layout consists of a H ‐plane T ‐junction, whose ports are characterised by the same cross‐section. The output ports are both closed with a metallic screen and energy is allowed to pass through by means of a vertical slit drilled into each metallic screen. To make the transmission efficient, two identical particles, printed on the two faces of a dielectric slab, are placed across the slits. Depending on the design, at the resonant frequencies of the two bi‐omega particles, either balanced or unbalanced power splitting is obtained between the two output ports. A proper set of numerical simulations and measurements confirm the effectiveness of the proposed design, which can be successfully used for realising compact and highly selective waveguide power splitters.
