The Ka-band (26.5-40 GHz) standard waveguide (WR28) to 50Ω Coaxial (2.92mm Female) microwave transition has been designed indigenously. This is a short-ended ridged waveguide design with disc-loaded coaxial probe [1] based on the principles of fiel

Directional couplers realized in microstrip parallel coupled line configuration exhibits very poor directivity. Inhomogeneous nature of microstrip circuits generate even and odd modes of wave propagation having different phase velocities, which in tu
