Antenna and wave propagation solved problems free#
Know the principles of operation of simple antennas, near- and far field, polarization, losses and directivity, be able to design antennas, antenna systems and calculate key quantities related to them. solve problems involving plane waves propagating in free space and various material media, solve problems involving spherical waves, solve problems involving plane waves incident upon material boundaries and, solve problems involving di raction by a knife edge.Know planar electromagnetic waves, their propagation through different materials and be able to calculate or determine key quantities related to them, such as the Pointing vector, power, polarization, reflection and refraction of electromagnetic waves.Be able to use Maxwell‘s equations to describe simple time dependent electromagnetic phenomena.According to ITU-RP533, a general HF radio wave propagation model is established by. In some situation the electric field E is parallel to the wave propagation that condition. Normally the electric field E is perpendicular to the direction of wave propagation. The power output was fed to a transmission line with attenuation of 0.5 dB/m. One hundred watts power output was derived from the final stage amplifier of a transmitter of a station which is 10 km away from a receiving station. Antenna is also said to be an impedance transforming device. Problem Solving on Wave Propagation and Antenna. Be able to formulate and solve electrostatic and magnetostatic problems for simple geometries with boundary conditions. characteristics of HF radio waves on the sea and solve related problems. Antenna is a transition device or a transducer between a guided wave and a free space wave or vice-versa.Know and be able to calculate quantities related to voltage and current signals propagating along transmission lines, characteristic impedance, standing waves, the effect of load on reflection along the transmission line, use of the Smith Chart, and impedance matching with line stubs.(When the dimensions of an object are measured in wavelengths, we call this the electrical size of the object.) 2,500 solved problems in fluid mechanics. Troposphere wave, Yes wave- tilt of the surface wave, No 52. A.R.Harish, M.Sachidanada, Antennas and Wave propagation, Oxford University Press, 2007 Page : 330 - 381 50. If the separation is smaller, then the antenna will tend to smooth the an-gular separation distance. Ground wave propagationand Conductivity of ionized gas, Faraday rotation, No 51. At the completion of the course students are expected to ANTENNAS the gain of an antenna is proportional to its size measured in wavelengths.
