Novel Empirical Equations to Calculate the Impedance of a Strip Dipole Antenna

Abstract

This paper investigates the input impedance of strip dipoles since they are the basic elements of folded strip dipole antennas. A novel, simple and accurate design algorithm is presented. Compared to state-of-the art design equations, the new proposed equations are more accurate than those found in the literature and take into consideration the antenna feeding width. These equations reduce the calculation time, when compared to commercial electromagnetic simulation software, allowing for fast antenna designs with very high accuracy. Based on the novel equations, a strip dipole antenna is designed, simulated, manufactured and measured. The simulation results are validated by measurements.
