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.


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.


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


What two types antenna used for terrestrial microwave communication?

Virtually all terrestrial microwave communication is point-to-point, using parabolic reflector antennas. A small percentage uses yagi, helical, corner reflector, or flat-plate reflector antennas. Essentially no "omnidirectional" antennas are used in microwave.

Which type antenna used for radar communication?

Radar and communications are two different applications of radio waves. For radar, directional antennas are used, and the normal antenna for a ship installation would be a parabolic reflector with a rectangular aperture about 5 times wider than its height. This gives a narrow beam in the horizontal direction, and pulses are sent out and detected after being reflected by the target.


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.
