Design of a Magneto-Electric Dipole Antenna for Fm Radio Broadcasting Base Station Antenna Implementation

Abstract

Abstract-This work presents the design of a magneto-electric dipole (MED) antenna for the base station antenna of FM radio broadcasting implementation. The advantages of MED antenna are high gain, stable and symmetrical radiation patterns in both electric and magnetic planes, and low back lobe radiation pattern. The antenna was designed and studied to achieve the optimal dimensions of configuration parameters. The prototype antenna was fabricated and measured to validate its S 11 , radiation patterns, and gain. The impedance bandwidth was 33.49%, and the average gain was 7.78 dBi at the entire operating frequency (88-108 MHz). The measured results are in good agreement with the simulated ones.

Numerical Extraction of the Equivalent Circuit for a Basic Magnetoelectric Dipole Antenna

“…Notably, the implementation of a co-simulation between the basic ME dipole and its front-feeding circuit necessitates an equivalent circuit model of the antenna. Thus far, many equivalent circuit models have been proposed for this kind of antenna [20][21][22][23]. However, these models failed to reveal the real impedance characteristics of the antenna.…”
