Meaning and Definition

A type of radio antenna consisting of a dipole with its ends folded back and connected to form a closed loop, providing increased bandwidth and impedance compared to a simple dipole.

In broader technical contexts, it refers to any antenna design based on this folded-wire principle. It is never used metaphorically outside of antenna theory and radio engineering.

Watch out

Common Mistakes When Using “folded dipole”

  • Pronouncing 'dipole' as /ˈdɪp.əl/ (like 'dip' and 'pole') instead of /ˈdaɪ.pəʊl/.
  • Using it as a verb (e.g., 'He folded dipole the wire'). It is strictly a compound noun.

FAQ

Frequently Asked Questions

Not exactly. While a folded dipole forms a closed loop, it is specifically a one-wavelength loop with a particular feed configuration. A general loop antenna can be of various sizes and shapes.

Mainly for its higher input impedance (often around 300 ohms), which is a better match for common twin-lead transmission lines, and for its slightly wider bandwidth.

Yes, folded dipoles have historically been common elements in traditional television and FM radio receiving antennas due to their favourable impedance and bandwidth properties.

No, 'folded dipole' is a highly specialized term confined to the fields of antenna design, radio frequency engineering, and amateur radio.

Folded dipole is usually technical/highly specialized in register.

Folded dipole: in British English it is pronounced /ˌfəʊl.dɪd ˈdaɪ.pəʊl/, and in American English it is pronounced /ˌfoʊl.dɪd ˈdaɪ.poʊl/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Imagine a wire dipole antenna that has been folded back on itself like a loop, which folds the impedance (makes it higher).

Conceptual Metaphor

N/A (Purely technical, literal term).
