The isolation of two different feed networks for antennas is presented. This is quantitatived by the reappearing voltage at the antenna elements due to the reflection at the network junctions. The voltage is formulated for the general case of antenna

The exact solution for the electromagnetic field diffracted by a perfectly conducting slotted elliptic cone is determined. The solution is presented in the form of a dyadic Green's function, which is the most general form of a possible solution. Some
