Abstract :
In this paper some investigations concerning on waveguide loop coupler with flat coupling characteristics are presented. The approximate formulas enabling the calculation of its basic electrical parameters are widely described. For waveguide working near to the cut-off frequency the distortion of coupling flat characteristics is observed. The way of reducing these distortions is presented and discussed.
