Short Dipole
The simplest of all antennas. It is simply an open-circuited wire, fed at its center
The words “short” or “small” imply “relative to a wavelength” size of the dipole antenna does not matter.

Dipole
Two monopoles facing away from each other
Used to greate a powerful signal in restricted space
|
|
Half-Wave Dipole
Special case of the dipole antenna
Length of this dipole antenna is equal to a half-wavelength
|
|
Broadband (Wideband) Dipoles
Broadband by increasing the radius A of the dipole
|
|
Monopole (Whip)
Works best for narrow range and can be collapsible
Used on small radios and vehicles
|
|
Folded Dipole
Folded dipole forms a closed loop
|
|
Loop
Works like a dipole and reach multiple frequencies.
Commonly used for TV and RFID systems

|
Cloverleaf
Circularly polarized wire antenna, with a radiation pattern similar to a dipole antenna
peak radiation direction broadside to the antenna. The antenna has nulls (very little radiation) in the axial direction
