Receiving antenna design for miniature receivers

A design procedure is described which determines the minimum required volume and the optimum dimensions for a ferrite loaded loop receiving antenna. The frequency of operation, bandwidth, transmitted signal strength, desired signal-to-noise ratio, receiver sensitivity, and the relative permeability of the ferrite are required to determine the design. Useful approximations for flux averaging, demagnetization factor, atmospheric noise, and chassis loaded

are given.
