Abstract : The modified diakoptic theory is extended and further developed so that it can be used to analyze antenna arrays comprising both microstrip-fed, microstrip radiator elements on grounded substrates and stripline-fed, slot-in-plane radiator elements. Analysis of such structures by the modified diakoptic theory is a very efficient antenna array solution method. Results obtained on model arrays are in close agreement with those computed by the method of moments as well as with data measured in the laboratory, confirming that the technique is also accurate. In addition, a new stripline-fed slot antenna element has been introduced and investigated analytically as well as experimentally. This array element is amenable to theoretical analysis and does not suffer from the parallel plate resonances typically associated with the finite-size of the parallel plates of a practical stripline. The computed data agree closely with measured results and provide the basis for accurate design of stripline-fed slot arrays without excessive experimental trial and error.
