The current is maximum and voltage is minimum at the center of the dipole antenna. Conversely, the current is minimum and voltage is maximum at the ends of the dipole antenna. The radiation pattern of the basic dipole antenna is shown in the figure below. It is perpendicular to the axis o...
What is a Collinear Antenna?Antennas 1 Answer Can you answer this question? Answer Editorial Team - everything RFAug 13, 2018 In geometry, a set of points are collinear to each other if they lie on a single line. In telecommunications, when two or more dipole antennas are vertically ...
The driven element of a Yagi is equivalent of a center-fed, half-wave dipole antenna. Parallel to the driven element are straight rods or wires called reflectors and directors. A reflector is placed behind the driven element and is slightly longer than driven element; a director is placed ...
One form for the VHF antenna is the dipole antenna, sometimes referred to asbunny earsorrabbit ears, designed for indoor use. It is also found combined with a UHF loop. On the other hand, theYagi antenna, which originated in Japan — also called aor aUda-Yagi antennain order to include ...
A coaxial antenna is a dipole antenna, meaning that it has two conductive elements. One side of the element is mounted to a hollow metal tube. The tube functions as an outer conductor. Coaxial cable is passed into this tube and connected. An inner conductor is mounted on top of the tube...
J pole antenna : This type of vertical antenna is a convenient for of vertical antenna. It provides some gain over a quarter wave vertical and has the advantage that it does not require any radials or some form of ground plane against which to operate. Vertical dipole: The vertical dipole...
No INS is perfect, so inaccuracies will accumulate the longer the system is a dead reckoning. In the case of submarines, they are often located underwater so deep that they cannot deploy an antenna that floats to the surface and connects to GPS and other GNSS systems in space. So when ...

Figure 13: Parasitic capacitance forms an electric dipole antenna 3. How to solve the influence of parasitic capacitance Parasitic capacitance is often the natural enemy of EMC engineers, and the reasonable and appropriate handling of parasitic capacitance problems has become a huge test for EMC engin...
Dipole as an Antenna In physics, another definition of a dipole is an antenna that is a horizontal metal rod with a wire connected to its center.
