Radiation resistance of quarter wave monopole antenna is?
The radiation resistance of quarter wave monopole is 36.5 ohms
The most appropriate value of the radiation resistance of a quarter wave monopole antenna?
The radiation resistance of a quarter wave monopole over a ground plane is 36.5 ohms.
What is the difference between monopole antenna and dipole antenna?
Monopole is an antenna with just the radiating element where the ground of the transmitter is connected to an electrical ground which serves as an Image ground to the radiating element. Thus the name "mono" pole. Dipole is where the ground and the radiating elements are connected to two different elements where one is the radiating element and the other is the ground to the later. Thus the name "Di" Pole Cheers by zafran khan
A disturbance sends ripples across water in a tub these ripples example of a?
wave front. radio waves do the same thing when emitted by a monopole antenna
How do you configure a monopole antenna on a frequency lower than the resonant frequency?
You can use an inductor or capacitor circuit to electrically lengthen or shorten the antenna. I cant remember which circuit does which but that's how antennas are efficiently used for several frequencies.
When a short grounded vertical antenna has a length L which is 0.05 1 at frequency f and if it's radiation resistances at f is R Ohms then its radiation resistance at a frequency 2f will be?
In ideal conditions the radiation resistance of a short antenna is proportional to the square of the height in wavelengths. So doubling the frequency would produce 4 times the radiation resistance. Rr is 1578(He/lambda)2 for a short antenna, He < lambda/8. He is the effective height, equal to half the physical height for a simple monopole, rising to the physical height for a monopole with an infinite amount of horizontal top loading.
Glass antenna mean in cars?
Means you don't have an antenna on the roof, but rather a sliver of metal taped to the windscreen, acting as an antenna.
What does antenna power overload mean?
it means take the antenna out of the power outlet, it won't work!
What is potential difference of a monopole?
The simple answer: the potential at a point some distance, r from a monopole is kQ / r, where k is Coulumb's constant: 9.0E9 Q is the charge of the monopole and r is the distance from the monopole. And how to get there: Since electric force is kq1q2/ r2, the electric field ( Force per charge) is kQ/r2. The voltage of a particle is defined to be the integral of the electric field with respects to r. Thus integrating you get the above equation.
What does spiky combers of the air mean?
An antenna
How do you get to the other antenna on Poptropica?
if you mean in spy island than you use ur bow tie to get to the antenna
Would bad signal on a T.V. mean a problem with the antenna?
Yes, a bad signal on a TV mean that there is definitely a problem with your antenna. It could be that it's not working well for your television. It could also be old and it could also mean that you need to move the antenna around to get a good reception.
