Does shape of the antenna effect the magnetic field?
Yes for instance a dipole will have a doughnut shape field and a directional like a yagie will have a long teardrop shape field at the front end and a shorter teardrop field at the rear and some smaler fields sideways and a parabolic disc wil have a very long teardrop shape field
What are the Bending moment diagram for simply supported beam with udl?
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
What is a reconfigurable antenna?
an antenna that is able to be formed, or bent
Can you replace an XM radio antenna with any other antenna like a 3ft hard cb antenna?
You can replace an XM radio antenna with a CB antenna, a ham 40-meter mobile antenna, a cellphone antenna, a GPS antenna, a TV antenna, a wire coat hanger, a 6 GHz microwave antenna, or a chain of paperclips. However, since none of them is optimized to operate at the frequencies of XM radio, like the XM antenna is, none of the others will work as well. Most of them will likely be so inefficient at the satellite radio frequencies that when you use one of those, you hear nothing at all on your radio.
Are Passive reflectors used in both Active and passive Satellite system?
Yes. The most common antenna for satellite systems is the 'Dish'.The dish is a parabolic , passive, reflector.It merely reflects and concentrates the signal to the LNB receiver.Transmission also works this way, bouncing the signal off the dish, to concentrate it in one direction, in a narrow beam.
What are the material is used manufacturing Parabolic reflector antenna?
A parabolic reflector antenna is made of fiberglass or metal (usually aluminum).
What type of antenna is used for satellite communication?
parabolic
Why the parabolic antenna has parabola shape?
Parallel rays, such as those from a very distance source, are focussed by a parabolic antenna so that they all meet at the focus of the parabola. This results in a stronger signal.
Why might a parabolic reflector horn type microwave antenna be preferable to a parabolic dish type microwave antenna?
The reflector horn type antenna has greater "side lobe" rejection, directionality and sensitivity (efficiency) than a dish type.
Is there a platinum in parabolic disc antenna?
It would be a waste of precious metal if there was.
Why antena is in parabolic form?
A: For the same reason a heater is parabolic to reflect heat, For the antenna the opposite is true to focus the incoming waves
What is the difference between directed antenna and parabolic dish?
about 40 db about 40 db
What is a spherical dish antenna required for satellite tv reception?
The parabolic antenna is really not an antenna at all - but a collector/reflector, which catches and concentrates RF (radio frequency) into a tiny antenna mounted above the dish, pointed into the dish. Since satellites transmit at very high frequencies (microwave), the actual antenna can be shorter than one inch. To strenghen the signal and make aiming the antenna at the satellite easier, the parabolic reflector picks up a wider area of RF.
What are the common shapes for antenna reflectors?
A lot of parabolic reflectors are used in antennas, particularly with frequencies in the microwave region. There are a few other shapes, but they are infrequent choices for antenna designers.
How do dogs' ears shapes help them hear?
The shape acts like a parabolic antenna, focusing sound into the ear from a larger surface area. Simples.
Why we use patch antenna in communication?
because patch antenna are used in order to achieve higher gain small dimensions, light weight, slim size and easy manufacturing as compared with parabolic dish or other antenna's
How could a person boost the strength of a wireless antenna?
One way to boost the signal of a wireless antenna is to upgrade to a high-gain antenna. Other methods include adding a USB adapter with an additional external antenna or even to create a parabolic dish using a soda can.
