A dipole antenna is really a small radio antenna that is made from a simple wire, it is made from 2 metal conductors, the voltage for the antennas are applied in the middle of both conductors.
They are simple antennas that are most often found in televisions and more appropriately named "Rabbit ear antennas" Everyone will be aware of this antenna as at some time a lot of people would have had the rabbit ear antennas for any portable television set in their house.
General antennas are typical on older household televisions sets and the kind of antennas work off radio waves. The signal gets transmitted via the radio waves and gets pickedd up through the antenna. A lot of people, maybe even yourself, has made an extremely crude dipole antenna through a metal coathanger. I remember 1 time once i was younger when my normal ariel stopped working I created an ariel for any tv in my room having a metal coathanger, when works very crudely the same way a dipole antenna does as it covers the signal and transfers it to the television set via the metal coathanger.
There exists a lot of information available about dipole antennas and how you can make your own but you need to be certain of the strength you need in the ariel which depends on the kind of components you put inside them. There is a lot that you need to know about radio waves and the sort of conductors you have to get a stronger signal as well as the way you place the antenna together to get the best possible reception.
If you are searching for more information on emi shielding where to buy the materials and how to construct a dipole antenna then there exists a few places that you could look to get all the information which you will need to achieve this.
