Different Frequency Range Distribution

This table might not provide all the necessary information for specific frequency range.

No hard and fast rule for opting an antenna for a particular frequency be there.

Many electrical factors (eg radiation efficiency, radiation pattern, maximum antenna gain, antenna impedance, frequency characteristics) and structural factors (eg shape, size, appearance, cost and other economic aspects) are to be taken into account.

Band Frequency Range Wavelength Services Remarks
ELF 3 Hz – 3 KHz Audio signal
VLF 3 – 30 KHz 100 – 10 km World-wide Telegraphy for ships, mine and marine   communication Audio and military navigation
LF 30 – 300 KHz 10 – 1 km AM Broadcasting, Long distance point-to-point   services, Navigation
MF 300 – 3000 KHz 1000 – 100 m AM Broadcasting, Navigation, Harbor telephony General MF antennas– center-fed or folded   dipoles 

Broadcasting antennas– inverted L or T   antennas

HF 3 – 30 MHz 100 – 10 m SW Broadcasting, OTH (Over the horizon) Radars General HF antennas– Half-wave antennas,   arrays like Yagi 

For TV transmission– Center fed dipole

 

For Communication– Fan dipole+loop+vertical   whip antennas

VHF 30 – 300 MHz 10 – 1 m FM, TV, Radar, Short distance communication,   Aircrafts and Ships Navigation, Telephony Horizontal Polarization used, Horn+Corner+Parabolic   Reflectors used, Slot radiators, Yagi arrays 

Broadband antennas ( conical unipole,   conical dipole, biconical, discone antenna)

 

All-around coverage given by   vertical+horizontal+circular polarization

 

For mobile – fin aerial antennas used

UHF 300 -3000 MHz 100 – 10 cm LoS + Sate Comm 

TV, short distance communication, Radar, LAN,   Cellular Mobile communication, GPS, Aircrafts Navigation, Aircraft Landing

SHF 3 – 30 GHz 10 – 1 cm LoS + Sat Comm 

Radar, Radio and TV relay links, Satellite   Communication, Data transmission

Antennas used are horms, reflector antennas and   lens antennas of different types.
EHF 30 – 300 GHz 10 – 1 mm LoS + Sat Comm 

Millimetric wave Radars, Amateur

300 – 3000 GHz < 1 mm Experimental applications
