Antenna is a Active or passive devices?
it depends on existing amplifier or not , if after antenna there's an amplifier it called active else it called passive which less sensitive that active .
End fire antenna?
end-fire antenna = surface-wave antenna
What is thin linear antenna?
A thin antenna has nothing to do with the physical size of the antenna. Any antenna whose length is less than (1/10) of the wavelength of the signal is thin antenna. A linear antenna is one in which the current distribution is linear or bears a linear relationship with some parameter, say voltage of the antenna...... Mukesh

Is the inductor a passive component or active component?
passive
Is antenna passive or active component?
An active antenna is an antenna which has an amplifier attached very closely to it. The antenna/amplifier system is called an active antenna. It is used for receiving signals only. The idea is to set the signal-to-noise ratio (SNR) before the signal travels along a transmission line where it is susceptible to interference and loss.
Antenna is a Active or passive devices?
it depends on existing amplifier or not , if after antenna there's an amplifier it called active else it called passive which less sensitive that active .
How do you prepare a passive RFID TAG?
By using an antenna
Why radar antenna is an example of power amplification?
On its own, it isn't. Amplification requires input of energy - an antenna is entirely passive.
Is an Aeriel on the roof a standard or an active antenna?
An active antenna is powered antenna, this includes a RF amplifier and a power supply so it must be "plugged in" somewhere. A standard "passive" antenna has no amplifier.
If antenna is passive than how can it add gain?
Antennas provide so called passive gain, which means it comes from particular shape of the antennaThe gain of an antenna is a passive phenomenon - power is not added by the antenna, but simply redistributed to provide more radiated power in a certain direction than would be transmitted by an isotropic antenna. If an antenna has a gain greater than one in some directions, it must have a gain less than one in other directions, since energy is conserved by the antenna.SOURCE: wikipedia.com
Is an antenna active device?
In electronics any device that just pass along a signal by its characteristics is defined as passive.
Are Passive reflectors used in both Active and passive Satellite system?
Yes. The most common antenna for satellite systems is the 'Dish'.The dish is a parabolic , passive, reflector.It merely reflects and concentrates the signal to the LNB receiver.Transmission also works this way, bouncing the signal off the dish, to concentrate it in one direction, in a narrow beam.
Antenna Boosters Increase the Surface for Cell Phone Reception?
Cell phone antenna boosters work much like satellite dishes by helping to capture and emit stronger signals. This, in theory, means stronger and clearer reception. The quality of the boosting antenna, however, is often related to the price of the device. As a passive device, the antenna booster is placed behind the phone's fixed antenna or on the rear surface. Booster antennas provide larger surfaces for cell phones to receive signals from transmitting towers.
What is the definition of power gain in antennas?
An antenna is a completely 'passive' device. It can't radiate more power than youput into it. But if you know what direction you want it to favor, you can design theantenna to take the power away from directions you don't need, and concentrate itin the direction you want.Antenna gain means the strength of the antenna in its best direction, comparedto a theoretical ideal antenna that's exactly equally good in all directions (known asan "isotropic" antenna).
Difference between hertz antenna and marconi antenna?
Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
What is the difference between an active antenna and a standard antenna?
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
