Antenna Efficiency

Antenna Efficiency

In antenna theory, antenna efficiency is a loose term usually meaning radiation efficiency, often abbreviated to efficiency. It is a measure of the efficiency with which a radio antenna converts the radio-frequency power accepted at its terminals into radiated power.

Antenna (radio) - Parameters - Efficiency
... Efficiency of a transmitting antenna is the ratio of power actually radiated (in all directions) to the power absorbed by the antenna terminals ... The power supplied to the antenna terminals which is not radiated is converted into heat ... This is usually through loss resistance in the antenna's conductors, but can also be due to dielectric or magnetic core losses in antennas (or antenna systems) using such components ...

Famous quotes containing the word efficiency:

    “Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.
