Abstract
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 designed using direct coupling between two waveguide structures and cutting in narrow walls. This cutting in waveguide narrow walls controls the coupling and the phase differences of the coupler outputs. The simulated reflection and isolation coefficients are observed to be less than -20 dB at 26 GHz, with transmission coefficients ranging between -2.97 dB and -3.04 dB. The phase differences -90° is observed at the outputs. Overall, the waveguide coupler shows a great potential for Ka bands applications.
