9.33 An antenna with a circular aperture has a circular beamwith a beamwidth of 3◦ at 20 GHz.(a) What is the antenna directivity in dB?(b) If the antenna area is doubled, what will be the newdirectivity and new beamwidth?(c) If the aperture is kept the same as in (a), but the frequencyis doubled to 40 GHz, what will the directivity andbeamwidth become then?
