摘要：

The magnetic field and related current density behavior are investigated on the surface of printed conductors with polygonal contour used in MIC circuit components and antennas. From the rigorous E solution for the plane sector perfect conductor, we determine the H singular solution. We formulate a convenient singularity function that just represents the boundary conditions and the singularity distributed along the conductor edge. The singularity function is explicitly reported for the commonly encountered 90-degrees and 270-degrees plane sectors and 90-degrees bitriangular antenna, whereas its systematic generalization is indicated for sectors of arbitrary aperture and composite configurations and polygonal path.
