I am a B.Tech 3rd ear completed student.
I am doing a project on AUTOMATIC DISH ANTENNA POSITION CONTROLLER.
I need know complete details of this like

Where it has been using?
Where it has been implemeneted?
Why it had came intio existence?
What risk it has been elimenated and what?

An antenna is defined by Oxford Dictionary as ? a usually metallic device for radiating or receiving radio waves ?. The IEEE Standard Definitions of terms for Antennas ( IEEE Std 145-1973) defines the antenna or aerial as ? a means for radiating or receiving radio waves ?. In other words the antenna is the transitional structure between free-space and a guiding device. The guiding device or transmission line may take the form of a coaxial line or a hollow pipe (wave guide) and it is used to transport electromagnetic energy from the transmitting ....etc

Abstract

The main scope of the project is to control the Dish antenna from a remote area.
Stepper motors operate differently from normal DC motors, which rotate when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple toothed electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit, such as a microcontroller.
To make the motor shaft turn, first one electromagnet is given power, which makes the gear's teeth ....etc

In paper based financial messaging system, the messages are sent in defined formats duly signed by the authorized signatories. Paperless initiative and changes in the business practices have changed the authorization process. In electronic messaging, the messages are created, authenticated electronically and sent through electronic medium. Present technology facilitates data transmission with security integrity duly taking care of confidentiality and nonrepudiation of messages. Encryption and digital signature play a vital role in providing suc ....etc

The device was developed by Ramirez and Roger Green in the university of Warwick?s engineering department. It brings benefits to wireless networks, electronic households and data transfer. It applies techniques used to manipulate radio frequency to select the incoming ?signal frequency ? carried on the infrared beam to produce the optical equivalent of the radio. Optical antenna serves the same purpose as in electronic one .It must collect energy from an area and channel it t o the receiving element. Optical antenna uses a combination of precis ....etc
