The directional couplers are important microwave devices. There are many different types of couplers. The common ones are strip line coupler and waveguide coupler. In practical applications, couplers ...
This paper proposes a compact 10 dB broadband directional coupler, which is constructed from two parallel E-plane rectangular waveguide with three apertures and three metallic posts attached on the ...
Abstract The difference between phase velocities of the odd and even modes in inhomogeneous microstrip coupled lines makes the microstrip directional coupler a poor device regarding directivity. In ...
