Single-Conductor Transmission-Line Model for Bent Wire Structures

A bend in a single-conductor line is primary cause of radiation associated with the antenna mode; conversely, fed back, resulting attenuation and distortion current waveform. Despite being fundamental phenomenon, its dynamics have not been sufficiently characterized. Therefore, this study presents transmission-line model for bent wire structures comprising multiple straight elements by using local variables charge per-unit-length along thin conductor. The proposed validated over wide frequency range method moments. total distributions that an external field induces on structure are classified into three components: scattering source distribution, traveling wave corresponding to Sommerfeld mode, reaction. These components suggest overall field-line coupling process: initially, electromagnetic structure, which turn drives radiation-reaction currents at ends, propagation accompanied losses. presented advantageous designing phenomena antennas metamaterials addressing interference problems passive circuit elements. case makes use precise descriptive included predict emissions mode around bend.
