Study of an End-Fed Dipole Antenna Excited by a Rectangular Waveguide

Abstract

We present the results of analysis of a dipole antenna fed via a rectangular waveguide and based on a recently proposed end-fed dipole. Both the radiation resistance and the complex input impedance of such an antenna are determined using the mirror image theory and the induced EMF method. The principles used for an optimal choice of the radius of the antenna conductors and the size of the wide wall of the waveguide are discussed. The experimental results indicate that the proposed approach is correct.
