1.	In which of the following radiators are combined into sub-arrays and then fed to elements in end or center fed?(a) Parallel feed(b) Series feed(c) Optical feed system(d) Series end feedThe question was asked in a national level competition.The above asked question is from Phased Array topic in division Phased, Adaptive and Binomial Arrays of Antennas
Answer» The correct option is (a) Parallel feed Best explanation: In parallel feed, a NUMBER of radiators are combined into sub-arrays and then to elements in series or center fed. In series END fed, the radiator is placed at the end of the array and its electrical path length depends on the frequency.In optical feed SYSTEMS power is DIVIDED in one STEP.
