| Abstract: | By using the quasi-optical theory,the beam transformation characteristics of large aper-ture parabolic reflector antennas are analyzed.The relations between antenna behavior,radia-tion beam dimensions,and feed beam dimensions are discussed.The possibilities for antennadesign in terms of the quasi-optical theory are investigated.Finally,useful results are present-ed in the form of formulas. |
