radiation resistance in a sentence

Examples

1. The radiation resistance of the dipole increases with this spacing, so the spacing can be adjusted to match the driven element to the feed line.
2. Consequently, it can be seen that the radiation resistance computed for the short dipole is one quarter of that computed above for the Hertzian dipole.
3. As the current is the same, the radiation resistance ( real part of series impedance ) will be half of the series impedance of a half-wave dipole.
4. In all these antennas the smaller radiation resistance of the short radiator is increased by the capacitance added by the wires attached to the top of the antenna.
5. This led to the consideration of the use of gamma radiation as a food preservative, and Anellis began research on the radiation resistance of bacteria in canned foods.
6. This method can be used to compute the radiation resistance for any antenna whose far field radiation pattern has been found in terms of a specific antenna current.
7. They are used as transmitting antennas below 1 MHz, in the electrically short antenna, and by itself would have very low radiation resistance and be a very inefficient radiator.
8. Resonating such an inductor with a capacitor at the frequency of operation not only cancels the reactance but greatly magnifies the very small radiation resistance of such a loop.
9. If ohmic losses in the conductors are neglected, the radiation resistance ( considered relative to the feedpoint ) is identical to the resistive ( real ) component of the feedpoint impedance.
10. Because they are short compared to a wavelength of the radio waves, they have low radiation resistance and are usually inefficient, radiating only a fraction of the power supplied by the transmitter.
