Today wireless technology is used in many applications well integrated into our everyday life. Planning a good, stable and reliable microwave network can be quite challenging. Careful planning and detailed analysis is required for a microwave radio system before the equipment can be installed. A poorly designed path can result in periodic system outages, resulting in increased system latency, decreased throughput, or worst case, a complete failure of the system. 1.1 Microwave/Radio Frequency Wave The term microwave refers to alternate current signals with frequencies between 300 MHz and 300 GHz with a corresponding electrical wavelength between λ = c/f = 1 m and λ = 1 mm respectively. Signals with wavelengths on the order of millimetres are called millimeters waves. The relation between the frequency f and wavelength λ being f λ = c, where c is velocity of propagation of the radio wave, which is equal to that of light waves in frees pace 3x108 m/sec. Any frequency within the electromagnetic spectrum associated with radio wave propagation is referred as Radio Frequency (RF). When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. 1.2 Wireless Communication The basic motto of communication system is to ensure the exchange of information in between the people. When this communications without wired then it’s refereed to wireless communications. Now a day this wireless communications gets more attention from the Communication industry and provide better quality information transfer between portable devices. Autonomous sensor networks, Multimedia, Video conferencing, Distance learning and Internet enabled cell phone are the Valuable Applications of this technology. 1.3 Radio Frequency / Microwave Applications The main part of radio
