What is a composite dipole antenna?
The stacked dipole antenna is a common antenna design that has two elements, correctly called poles, which are usually made of solid material. Both poles have one end close to each other, then stretching apart and then turned back or folded towards each other until they almost touch. Folded Dipo antenna design is the type of antenna with full wavelength used most often for FM radio intake.
The dipole antennas are designed to receive radio frequency transmission broadcasts by another antenna at a certain distance. When it sends an antenna, the electrical signal travels to the antenna feed, which is one end of each of the poles of the antenna. The electrical signal causes the antenna poles to resonate at frequency identical to the electrical signal with an antenna. As the antenna resonates, it creates an electromagnetic field that also corresponds to the frequency of the electrical signal. After the second antenna, it causes the poles to resonate in this antenna. This resonance causes the electrical signal to appear onAntenna feed, which is the same as an electromagnetic field causing resonance. This electrical signal then continues to various circuits to insulate and amplify the signal so that the radio finally creates a sound sound that corresponds to the original signal transmission from another antenna.
frequencies that antenna can receive or resonate is a direct function of the length of the antenna. Ideally, the antenna would have a length equal to the length of the radio waves to receive; Given that the radio wave of middle class FM is approximately 10 feet long, such an antenna would be very large and cumbersome. The dipole antenna helps with this problem using two poles, which are a quarter of the length of the radio wave, usually arrav direct line or parallel with each other.
By using two poles in this arrangement called half the wave dipole, the dipole antenna is able to resonate on radio waves that are doubleEM combined length of two poles. Although it improves the portability of the FM radio antenna, the electrical length of the antenna is still half full of FM radio waves. As a result, there are victims in terms of acceptance.
The construction of the compound dipole antenna begins with the length of two poles, each of which is half the length of the FM radio wave. The feed, one end of each of the two poles, starts close together so that they do not touch. The Poles then reach in the straight line. At a point of less than about a third of its length, each of the two poles bends into a large, sweeping radius until the passenger is towards the other and stops just before the meeting.
In this arrangement, the two pole -stored dipole antenna, each half of the length of the FM radio wave, equals the full electrical length of the FM radio wave. As a result, the antenna does not experience any of the standard dipole antenna. Thus, a folded dipole antenna can offer performance over a standard dipole antenna, but comparable in physical lengthé with standard dipole antenna.
