When was Multiband created?
Multiband was created in 1975.
What are the disadvantage of yagi-uda antenna?
bandwidth is less..
How can you design a multiband filter?
5 methods to design a multiband filter are: Windowing: Apply window to truncated inverse Fourier transform of desired "brick wall" filter Multiband with Transition Bands: Equiripple or least squares approach over sub-bands of the frequency range Constrained Least Squares: Minimize squared integral error over entire frequency range subject to maximum error constraints Arbitrary Response: Arbitrary responses, including nonlinear phase and complex filters Raised Cosine: Lowpass response with smooth, sinusoidal transition
Difference between hertz antenna and marconi antenna?
Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
Advantage and disadvantage of using antenna?
Advantages of Antenna:- -They are cheap and exhibit good gain. -It delivers good performance with a size less than a dipole antenna. -They are cheap and not simply de-tuned by hand movements. -The size is less than the whip antenna. It can be used for wideband applications. -It is a very directive antenna and provides a good amount of gain. -They are very simple and a bit antenna. They are practiced in smartphones due to their thin structure. -They are very small in size and are less affected due to environmental factors. They are separate components. -They are simple in design and are poorer in size. They are robust in nature. Disadvantages of Antenna:- -They exhibit a large size at a lower frequency. -The higher cost is a major disadvantage. A better ground plane is needed to achieve good performance. -They have poor addition, difficult to tune and are very narrowband. -The major problem of this type of antenna is difficulty in feeding it. -They are bulky in size. They are de-tuned by nearby objects very easily. -They are larger in size at a lower frequency and hence it is difficult to design them for frequencies less than 433 MHz.
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.
What is passive antenna?
A passive antenna is an antenna that is not powered by an amplifier.
What is better a yagi antenna or directional antenna?
A yogi is a directional antenna.
What is the possessive form of antenna?
The possessive form for the noun antenna is antenna's.
Block diagram of microwave communication link?
Transmitter => Antenna =========> Antenna => Receiver Receiver <=== Antenna <========= Antenna <= Transmitter
Advantage and disadvantage of v-antenna?
To increase the gain and directivity in the direction of interest the lengths of the legs are increased in proportin. This results in sidelobes cancellation.The major lobes added together. The radiation pattern obtained is much sharper. The drawback of v antenna is that it provides stronger minor lobes which results in wastage of power in the undesired direction.
