A Compact UWB Single-Layer Out-of-Phase Power Divider Utilizing Microstrip-Slot Line Transitions

A Compact Ultra-Wideband (UWB) single-layer power divider with the out-of-phase feature is proposed. UWB out-of-phase performance is obtained, using wideband microstrip-slot line transitions. All three ports are printed on a single dielectric substrate. The simulation and experimental results of the enhanced UWB power divider indicate stable phase characteristics, high impedance matching responses, and low insertion losses performances at the operating range of 2-12 GHz.
