Compact UWB power divider packaged by using gap-waveguide technology

We present the design of a new ultra-wideband (UWB) 3 dB power divider, packaged by using Gap Waveguide Technology. The power divider, a simple compact T-junction designed by using Klopfenstein taper technique, has a bandwidth of about 2-14 GHz, with the purpose of being used in a feeding network for the Eleven feed. Simulated and measured results of transmission and reflection coefficients are presented. Comparison of the power dividers between without packaging, packaged by a metal box and packaged with the gap waveguide technology has shown the superiority of the new design.
