Duststorms are significant meteorological phenomenon occur for a significant percentage of time in arid and semi arid areas especially at African Sahara and Middle East. Measurements at existing microwave links show that the duststorms can potentially result in serious attenuation in signal level especially at Ku band and higher frequencies with di

Ku-Band low noise amplifier has been designed with the gain of 8.90 dB and 2.19 dB noise figure for satellite receiver. The parameters are optimized by using Microwave Office Simulator (AWR) Ver. 2006. The size of the monolithic chip is 0.316mm2. The LNA is designed to operate at 12GHz.International Conference on Computer and Communication Engineer

Problem statement: The fade margin analysis of microwave propagation in areas affected by duststorm had been presented in this study. Approach: Based on long term duststorm data recorded in Riyadh-Saudi Arabia, the fade margin due to duststorm effects estimated. Results: The fade margin due to duststorm then derived under various water contents dur

On Saturday 7 July 2007, the New Seven Wonders Foundation, Switzerland, in its new ranking again declared the Taj Mahal as one of the Seven Wonders of the World. Taj Mahal of India is not just an architectural feat and an icon of luminous splendor but an epitome of enormous love as well. The Mughal Emperor Shahjahan (1592-1666) got built the Taj Ma

Wave propagation at higher frequencies is highly influenced by rain. The measured rain attenuation data was collected from January 1999 to April 2000 at 15, 23 26, and 38 GHz frequencies for terrestrial microwave links in Malaysia. This research investigated the effects of frequency on the fade slope. The fade slope was analyzed using the measured

Several climatic dynamic phenomena such as rain and turbulence can seriously affect the quality of satellite communications. This project presents the design and implementation of a data acquisition system. The system provides accurate vital information to facilitate proper analysis of anticipated problems so that solutions can be incorporated when

There is an ever increasing demand for radio-frequency (RF) spectrum by the nations of the world, in order to satisfy the growing demand for long-distance communications. As C-band (4/6 GHz) is already congested, and Ku-band (12/14 GHz) is filling up rapidly, currently interest focus on the utilization of higher bands. Some systems are already desi

Since Islam followed in the footsteps of Arab conquerors of Central Asia, it is sometimes heard that the religion was imposed by force on the region. This is a gross misconception unsupported by any historical evidence. The coming of Islam in the whole region took a comparatively short period of time starting in the mid-seventh century. Islam sprea

From simple boats,rafts and canoes they developed ships with masts which made it possible for human beings to roam around the various parts of the known world. Naturally the coastal people indulging in seafaring played a significant role in bringing nations closer

Generally speaking, media is extensively used as the means to disseminate news and information pertaining to business, social, political and religious concerns. A portion of the time and space of media has now become an important device to generate economic and social activities that include advertising, marketing, recreation and entertainment. The
