New source models for center-fed cylindrical dipoles

In this paper four simple source models are presented for the center-fed cylindrical dipoles. The method of moments (MoM) is used to test these sources by obtaining the current distribution and input admittance for different length to thickness ratios. The results are compared with the Gaussian and delta sources as well as the measured data. The MoM is then used to obtain the resonance lengths and the corresponding input resistance for the above four source models.
