Abstract: This paper aims to provide understanding of scattering and re-radiation by a receiving antenna through a detailed analysis of representatives from the simplest class of possible antennas, 1-dimensional antennas. Complete, exact solutions for the electromagnetic fields associated with such 1-dimensional environment and antenna structures can be obtained using only elementary analysis and functions. These exact solutions may be modeled by transmission line equivalent circuits. The paper carries this development further, reconciling the transmission line models with the traditional antenna equivalent circuit formulation and the scattering matrix representation of antenna theory, in the process explaining the various aspects of antennas: radiation, reception, scattering and re-radiation.
