Waveguide coupler using direct coupling aperture for Ka-band applications

This paper presents a waveguide coupler realized by direct coupling aperture at Ka bands. At high frequency planar coupler structures are expected to exploit a higher propagation loss and components losses. Therefore, a waveguide with direct coupling technology is proposed. A waveguide coupler is de...
