Abstract:

Further work on the ferrite-loaded biconical antenna has been initiated, with the object of evaluating the impedance, beam pattern, and efficiency. The problem of a ferrite-loaded, rectangular-cavity slot antenna has been formulated, and the variational procedure is being carried out to evaluate the impedance, radiation pattern, and the efficiency. The radiation patterns of the ferrite-loaded, rectangularcavity slot antenna have been measured and compared with the theoretical predictions of simpleaperture iffraction theory. Agreement with theory is good for the H-plane patterns and poor for the E-plane patterns. The effect of a flange is greater than expected. Author
