    About ten years ago, after a long struggle with our bureaucracy, I got a Tektronix 4051, with BASIC interpreter and 16 kB (kilobytes) of memory. I felt really happy, because I could edit programs and input data locally, even when all ports of the CDC 6500 were busy, or when the mainframe was not runnin for one of numerous reasons. But it still was a kght against the system, rather than working with a computer: Hours of data transfers and colleagues working on the same machine forced me to interrupt my investigations quite often View full abstract»

    The major topic of discussion at the Antenna bers on the subject, on how their organizations are posium was how to define the gam of active antenna antenna systems, and on what definitions would prove systems. (BY the term "active antenna system", what useful to the antenna community. In the end, the job is meant is an antenna system in which active devices of the committee is to develop standard definitions such as amplifiers, receivers, oscillators, Or 0 t h that are not only precise and correct, but are also active devices are embedded, so inextricably that the useful. passive antenna gain cannot be directly measured. An example is a phased array with individual transmitrecelve modules attached to each element in the Please send comments to the committee chair, array.) View full abstract»

    The brief discussion in this note suggests that reference to realized gains sheds a different light on practical performances of composite antennas, and that It might be indicated to reconsider whether the "old" IEEE definition of gain is still the best for application to modern antenna systems.

  • On the gain of large planar arrays

    For a large planar array of closed loops of dipoles, operated in one of its many possible resonant modes, the present definition of gain would seem to be preferable to that suggested by Dr. Roederer. There appears to be no reason for including mismatch losses into the definition of gain. The term gain or directivity should be reserved for properties of the field generated by the currents in the elements of an array. Losses in feeding and matching networks are important and need to be determined, but they are best kept separate from the radiated field and its directive properties, as expressed in the present IEEE definition of gain.
