Prediction of radiation losses and emission from a bent wire by a network model

This paper presents the modelling of the radiation characteristics of bent wires calculated through various approaches. The total radiation loss from a bent wire and the distributions of these losses are calculated analytically, leading to a rapid estimation of the maximum E field in the far field via directivity estimates. Also, an expanded Hertzian dipole approach based on the Cartesian frame is formulated, which facilitates the calculation of the E field in both the near field and the far field, and determines the radiation patterns from the bent interconnect by a simplified numerical process. Detailed radiation patterns from bent wires with various bend angles are presented in three-dimensional (3-D) parametric views and two-dimensional (2-D) polar views. The radiation characteristics are analyzed and compared to the simulations from Expert MiniNEC. Good agreement is observed.
