Thin Element Antennas
In the case of thin element antennas such as monopoles and dipoles, there is no simple relationship between physical area and effective area. However, the effective areas can be calculated from their power gain figures:
| Wire antenna | Power gain | Effective area |
|---|---|---|
| Short dipole (Hertzian dipole) | 1.5 | 0.1194 2 |
| Half-wave dipole | 1.64 | 0.1305 2 |
| Quarter-wave monopole | 3.28 | 0.2610 2 |
This assumes that the monopole antenna is mounted above an infinite ground plane.

Famous quotes containing the words thin and/or element:
“It is dangerous for a woman to defy the gods;
To taunt them with the tongue’s thin tip,
Or strut in the weakness of mere humanity,
Or draw a line daring them to cross;”
—Anne Spencer (1882–1975)
“We must be very suspicious of the deceptions of the element of time. It takes a good deal of time to eat or to sleep, or to earn a hundred dollars, and a very little time to entertain a hope and an insight which becomes the light of our life.”
—Ralph Waldo Emerson (1803–1882)
