In the paper, ‘Active antenna arrays, 1,’ I. B. Bott (UK) described the various forms of phased arrays that could be made and highlighted problems associated with active arrays. Particular reference was made to the active modules, dealing with their construction and with the assembly of such modules to make a satisfactory antenna.

K. Fujimoto (Japan) in the paper, ‘Active antenna arrays, 2,’ discussed the properties of an active antenna with a transistor circuit incorporated, having a variable pattern. He also discussed a multiplicative array, and pointed out the potential advantages of negative-impedance converters in active arrays.
