As part of a 1 GHz microwave communication system, a horn antenna with a directivity of 80 is purchased. The conduction and dielectric losses of the antenna are negligible, and the horn is polarisation matched to the incoming signal. A standing wave meter indicates a voltage reflection coefficient of 0.1 at the antenna waveguide junction. i) Calculate the maximum effective aperture of the horn. ii) If an electromagnetic wave with a uniform power density of 10 μWatts/m² is incident upon the horn, what is the maximum power delivered to a load? Assume that horn is connected and matched to the lossless waveguide?
