Short Dipole Antenna
Tiny antennas pack a punch by mimicking ideal dipole radiation despite their size
4 days ago

Why does a short dipole antenna have low radiation resistance, and how is this typically addressed in antenna design?
Because the antenna is short, it naturally has high radiation resistance, so no modifications are needed.
Because the antenna is much shorter than the wavelength, the current distribution is nearly uniform, resulting in low radiation resistance; designers use loading coils or capacitive hats to improve efficiency.
Short dipole antennas have low radiation resistance because they are made of poor conductive materials, which is fixed by using better metals.
