Question

Problem 5 The configuration shown below depicts two vertically oriented half-wave dipole antennas pointed towards each other, with both positioned on 100-m-tall towers separated by a distance of 5 km. If the transmit antenna is driven by a 50-MHz current with amplitude Io 2 A, determine: Reflecied 100m (a) The power received by the receive antenna in the absence of the surface. (Assume both antennas to be lossless.) (b) The power received by the receive antenna after incorporating reflection by the ground 10-3 surface, assuming the surface to be flat and to have er-9 and conductivity σ (S/m)
