Compact Inline Dual Band Dual Mode BPF with a Hybrid Structure of Single Layered

A compact inline dual-band dual-mode bandpass filter (BPF) using single-layered substrate integrated waveguide (SIW) is implemented by etching an H-shaped slot on the top surface of two adjacent rectangular cavities. The H-shaped slot consisted of two coplanar waveguide (CPW) resonators and two SIW
