  Antenna (radio) - Wikipedia, the free encyclopedia
Complex impedance of an antenna is related to the electrical length of the antenna at the wavelength in use.
The polarization of an antenna is the polarization of the signals it emits.
The Phased array antenna is a group of independently fed active elements in which the relative phases of the respective signals feeding the elements are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired directions.

 ANTENNA (RADIO) FACTS AND INFORMATION   (Site not responding. Last check: 2007-11-06)
Antennas have practical use for the transmission and reception of radio_frequency signals (radio, TV, etc.), which can travel over great distances at the speed_of_light, and pass through nonconducting walls (although often there is a variable signal reduction depending on the type of wall, and natural rock can be very defective to radio signals).
The bandwidth of an antenna may be increased by several techniques, including using thicker wires, replacing wires with ''cages'' to simulate a thicker wire, tapering antenna components (like in a feed_horn), and combining multiple antennas into a single assembly and allowing the natural impedance to select the correct antenna.
Antennas used for transmission have a maximum_power_rating, beyond which heating, arcing or sparking may occur in the components, which may cause them to be damaged or destroyed.

More specifically, an antenna is an arrangement of conductorss designed to radiate (transmit) an electromagnetic field in response to an applied alternating electromotive force (EMF) and the associated alternating electric current.
Antennas have practical use for the transmission and reception of radio frequency signals (radio, TV, etc.) which can pass through (nonconducting) walls at the speed of light over great distances.

 Generating a Domain-specific Thesaurus Automatically: An Experiment on FlyBase
By counting the numbers of terms generated by the subjects themselves and the system-suggested terms marked relevant (both somewhat relevant and very relevant) by the subjects, we were able to tabulate and analyze whether the thesaurus was able to contribute relevant terms during a retrieval process.
In conclusion, in terms of quantity, the thesaurus and the human subjects were able to generate the same number of relevant terms; but the contents of their lists were almost mutually exclusive.
However, they were very far down the list because their work was published many years ago, or not on the list at all because their work was published earlier than the range of years included in the database.

 "World BASE Fatality List" by Nick Di Giovanni, BASE 194
A major point to be taken into consideration, and one that is often missed, is the tens of thousands of successful BASE jumps that are made and that these listed events represent fatalities that have occurred over a period of time spanning 1981 to the present.
Kataya had made 2 BASE jumps prior to this incident and is originally on the BASE fatality list as details of this incident were being withheld by the parties involved.
Jo, the brother of Rick Stanley, #13 on this List, and another man are flying in a sailplane and for yet unknown reasons the sailplane crashes into a farmer's field.
