In this report, a dipole antenna fed by a coaxial line is taken up for the direction-of-arrival (DOA) estimation use and a new method to analyze the input impedance is proposed, where this antenna is supported itself and located over the ground. The method is derived using the equivalent model of the feed section as a circular radial line. Numerical simulations using the Method of Moment (MoM) and experimental results of a prototype model are shown to confirm the method. In addition, the mutual coupling is compared between the MoM and the experiment, and from the correspondence, it is also shown that this antenna can achieved a constant gain characteristic over the wide-band by optimizing geometric parameters. |
