Many different types of earth stations are required for satellite communications. The size of the earth station’s antenna is the primary feature distinguishing one earth station from another. The types are grouped under three headings: long earth station‚ short earth station‚ and very

An interrogation signal is send out from the ground (1030 MHz) through a rotational antenna to aircrafts flying in its sector. Aircraft equipped with transponders obtain these interrogations and send a respond back (1090 MHz) There are two primary types of interrogations: Mode A interrogations are used for plane identification information

CRUISE CONTROL DEVICE INTRODUCTION Everyday the media brings us horrible news on road accidents. Once a report said that the damaged property and other costs may equal 3 % of the world’s gross domestic product. The concept of assisting driver in longitudinal vehicle control to avoid collisions has been a major focal point of research at many automobile companies and research organizations. The idea of driver assistance was started with the ‘cruise control devices’ first appeared in 1970’s

At a very young age‚ when wave transmission and guided antennas were words unheard of for me‚ I wondered about the working of Television and Radio sets and I can very well say that a mystification at such an insignificant age has led to a passion for research thirteen years later. Now‚ I have actualized that awareness of the aspects of antenna design and identification systems with a strong EMW background would help me innovate and contribute to the active research in my chosen area of specialization

MIMO Techniques: 802.11n introduces smart radio technology to dramatically increase the quality and data rates by combining multiple antenna strategy with multiple simultaneous data streams. 802.11n systems uses MIMO (multiple input‚ multiple output) Fig. 1‚ techniques which can multiple transmit and multiple receive radio using its own antenna that also combine multiple streams of data of the same channel. 802.11n stations can multiply data rates using this spatial streams.
