Morphology
This is a straightforward noun–noun compound where 'dipole' specifies the type of 'antenna'; the meaning is compositional. If a learner knows 'dipole' (two‑rod, center‑fed element) and 'antenna' (device for transmitting/receiving signals), they can directly infer 'dipole antenna' as an antenna that is a dipole, so the structure is transparent.
Etymology
Dipole antenna gets its name from its simple shape: dipole means two 'poles', and the antenna is made of two straight metal rods fed in the middle. That's why a dipole antenna is a simple antenna with two rods that sends and receives radio signals.
