Definition
Meaning and Definition
An antenna with a four-lobed radiation pattern, resembling the shape of a four-leaf clover.
A specialized VHF or UHF antenna used for circular polarization, common in applications like amateur radio, satellite communication, and certain video transmission systems (e.g., FPV drones), where signal orientation consistency is required.
Dialectal Variation
British vs American Usage
Differences
British English uses 'aerial' exclusively in this compound. American English would typically say 'cloverleaf antenna', though 'cloverleaf aerial' is understood in technical contexts, often due to global terminology in radio hobbyist communities.
Connotations
Neutral technical term in both. The British usage sounds standard; the American usage might be perceived as slightly borrowing British terminology or being very hobbyist-specific.
Frequency
Very low frequency in general language. Slightly higher frequency in British technical/radio contexts than in American ones, where 'antenna' dominates.

Common Mistakes When Using “cloverleaf aerial”

- Assuming it is a general-purpose household TV aerial.
FAQ
Frequently Asked Questions
No. A cloverleaf aerial is a specialized antenna for circular polarization at VHF/UHF frequencies, used in hobbies like drone racing. A normal TV aerial is for linear polarization and receives broadcast television signals.
It is named for its physical shape and its radiation pattern (the way it sends/receives signal), which resembles the four lobes of a four-leaf clover.
It is not typical. Cloverleaf aerials are tuned for specific frequency bands (like 5.8 GHz for drones) and are designed for circular polarization, which is generally not used for standard Wi-Fi routers.
Its main advantage is circular polarization, which helps maintain signal strength regardless of the orientation of the transmitting and receiving antennas, reducing 'multipath' interference from signal reflections.

Cloverleaf aerial is usually technical (radio/telecommunications) in register.
Cloverleaf aerial: in British English it is pronounced /ˈkləʊ.və.liːf ˈeə.ri.əl/, and in American English it is pronounced /ˈkloʊ.vɚ.lif ˈer.i.əl/. Tap the audio buttons above to hear it.
