What is magnetic dipole antenna?
[mag′ned·ik ′dī‚pōl an‚ten·ə] (electromagnetism) Simple loop antenna capable of radiating an electromagnetic wave in response to a circulation of electric current in the loop.
What is method of images in physics?
The method of images (or method of mirror images) is a mathematical tool for solving differential equations, in which the domain of the sought function is extended by the addition of its mirror image with respect to a symmetry hyperplane.
What is dipole antenna design?
A dipole antenna includes two conductive elements like wires and rods or wires where the feeder at the center & radiating sections of the antenna are on either side. The metal wires’ length is half of the highest wavelength that is λ/2 within free space at the frequency of operation.
What is dipole antenna radiation pattern?
Dipole Antennas Include: The radiation pattern reflects the amount of power radiated from the dipole in any given direction. As the performance of the antenna is the same in transmit and receive, it also reflects the ‘sensitivity’ of the antenna in different directions.
How is magnetic dipole formed?
The orbit around the nucleus is equivalent to a current loop as the electrons are charged particles. The electrons revolve in anticlockwise while the current revolves in the clockwise direction. This movement of electrons creates a south pole and north pole resulting in atom’s behavior as a magnetic dipole.
How are magnetic dipole created?
An atom in which the centre of the negative cloud of electrons has been shifted slightly away from the nucleus by an external electric field constitutes an induced electric dipole. When the external field is removed, the atom loses its dipolarity.
What is the basic principle of the method of images?
The basic principle of the method of images is the uniqueness theorem. As long as (1) the solution satisfies Poissonʼs or Laplaceʼs equation and (2) the solution satisfies the given boundary condition, the simplest solution should be taken.
What are the characteristics of dipole antenna?
A dipole antenna commonly consists of two identical conductive elements such as metal wires or rods. The driving current from the transmitter is applied, or for receiving antennas the output signal to the receiver is taken, between the two halves of the antenna.
