Ankit Jain BTech 5 th Sem ECE IIIT Allahabad Features High Gain 3040 db Low cross polarization Reasonable bandwidth Fractional Bandwidth being at least 5 on commercial models. Series CRA antennas are available for operation over 18 to 325 GHz with standard reflector diameters ranging fr om 61524 cm to 4812192 cm depending on the frequency The main reflector has a highly accurate metalized surface and is constructed of eit Kang (KISTI). in collaboration with .

Is a structure which may be described as a metallic object, often a wire or a collection of wires through specific design capable of converting high frequency current into EM wave and transmit it into free space at light velocity with high power (kW) besides receiving EM wave from free space and convert it into high frequency current at much lower power (.

PagePage Abstract This report will define antenna theory and design as it relates to a Yagi-Uda Antenna type Antenna theory will originate from Electromagnetic field equations while expected design A Question of AccuracyAt one time it was a rule of thumb that the accuracy of parabolic antennas was fine if there was no divergence from the profile by more than 1/10 or 1/20 if you wanted a really four-mirror cavities.
