Abstract :
For investigation of plane waveguide structures circle sector finite element is proposed. Finite element of that form fulfils rand current conditions. Analytical expressions for orthogonal surface currents on such element are given. Properties of sector finite element are from element bent in waveguide cross section dependent. Use the sector finite element a noncoordinate waveguide exciter is investigated.
