operating at 433MHz. Our aim is to maximize the gain of the antenna and achieve impedance matching between load impedance and transmission line’s impedance. Among a wide range of different antennas‚ our group decide to build up a Yagi Uda antenna to fulfill this assignment for two main reasons. Firstly‚ the gain that Yagi Uda antenna provides is very high. Hence for transmission‚ Yagi Uda antenna makes sure all the transmitted wave to be directed to required area and for reception‚ it can receive maximum

TERRESTRIAL MICROWAVE COMMUNICATION SYSTEM DESIGN DESCRIPTION OF THE MICROWAVE BEAM: 1. The microwave beam behaves like a light beam and it tends to follow a straight line and azimuth. 2. The changes on temperature‚ pressure and relative humidity tends to refract the microwave beam. So it will follow on a slightly curved path. The radio horizon exists. 3. It is diffracted when grazing over an obstacle. A small shadow area created when some of the energy is redirected. 4. The beam
