~ Contributed by Ruturaj Rao

DIPOLE ANTENNA

A basic Half Wave (λ/2) Dipole Antenna
Effect of Fringing Fields on the physical length
Basics of Radiation Pattern, Field Regions and their types
Basics of Impedance Bandwidth
Wave Impedance in near and far fields

Analysis of variation of length depending on the location of feed point:

Effect of variation of length on the radiation pattern, current distribution and S11
(Feed point at the center)
Effect of variation of length on the radiation pattern, current distribution and S11
(Feed point adjusted)

NOTE: The simulations are performed using Antenna Toolbox of MATLAB R2023a software.
