What is the half wave dipole?
effective height of half wave dipole antenna
What is the value of radiation resistance of half wavelength dipole antenna?
36 ohm
What is the operational frequency of half wave dipole antenna?
Its resonant frequency is where its length is half a wavelength, so for 100 MHz the wavelength is 3 metres and a 1.5-metre long dipole is resonant. A dipole antenna can be used for many applications within a band of 10-20% around the resonant frequency.
How loop antenna and dipole antenna can be used interchangeably?
A full-wave loop antenna can be interchanged with a folded dipole without much difference. The input impedance is similar and the only difference is in the directivity: a full wave loop radiates along the axis of the loop, while a vertical folded dipole is omnidirectional.
What is the Application of Rhombic antenna?

What is the difference between yagi antenna and dipole antenna?
I don't think it has. Bandwidth depends on the diameter to length ratio of the antenna. The greater the diameter of the elements the wider the bandwidth. The inductance goes down and the capacitance goes up, giving the antenna a lower Q. the folded dipole has a greater effective diameter (at least double for the same materials). You can increase a normal dipole's bandwidth by increasing the diameter, hence the old time birdcage aerials.
What is the value of radiation resistance of half wavelength dipole antenna?
36 ohm
What are the disadvantages of half wave dipole antenna?
The half-wave dipole antenna has several disadvantages, including its limited bandwidth, which can restrict its effectiveness across a range of frequencies. Additionally, it has a relatively low gain compared to other types of antennas, making it less effective for long-distance communication. The dipole's radiation pattern can also lead to blind spots, limiting its directional capabilities. Lastly, it requires a specific length to function optimally, which may not be practical in all installation scenarios.

Is folded antenna nothing but the conical antenna?
A folded antenna is a dipole type.
Can you make a comparison between the dipole antenna and short dipole antenna?

Why dipole antenna not used for high frequency?
Depends on what you mean by high frequency. The rabbit ears antenna used in broadcast TV is a dipole and is used for VHF.
What is relation between antenna gain and beamwidth?
bandwidth refers to the amount of the frequency spectrum that a signal resides in.example, the spacing between channels on radio are determined by their bandwidth. beamwidth is a physical characteristic of an antenna. they generally mark the point bore sight of a directional antenna that are at -3dB or half power
The type of antenna used for the television broadcasting?
Dipole
What is Directivity of the small loop and short dipole has ratio?
The directivity of a small loop antenna is higher than that of a short dipole because the loop antenna is more directional and concentrates radiation in one direction. The ratio can vary depending on the dimensions and configuration of each antenna, but in general, the loop antenna can have a directivity several dB higher than the dipole.
What are the disadvantage of yagi-uda antenna?
bandwidth is less..
