a) A research paper presents a novel antenna which consists of a resonant slot in an aluminium plate. The slot is surrounded by a cavity and two corrugations. The proposed Ku-band antenna has an aperture efficiency of 74.3% and a measured gain of 12.2 dBi at 13 GHz. Answer the questions below. i) The equation below gives the relationship between the directivity of an antenna and its maximum effective aperture (Aem). Use this equation to derive an expression for the gain of an antenna in terms of its effective aperture. 4π -Aem D == 2² ii) Calculate the effective aperture and the physical aperture of the antenna. iii) If the directivity of the antenna is 14.3 dBi. Calculate the conduction dielectric loss efficiency of the antenna in dB.
