Wideband in-phase slot-coupled power dividers

A compact in-phase power divider is introduced. The proposed power divider consists of three metallic layers and two dielectric layers. The electromagnetic energy is coupled from a rectangular-shaped patch placed on the top layer of the structure to two one-half rectangular-shaped patches placed on the bottom layer of the structure through a rectangular-shaped slot cut into the common ground plane. It is shown that the bandwidth of the power divider can be controlled by the coupling value between the patches. Designing a sample of the proposed power divider for covering frequency range of 1-3.5 GHz is done. The simulation and measurement results of the designed power divider indicate the effectiveness of the proposed power divider.
