Direction Finding Antenna Interface 
--------------------------------------------------------------------------------

A microwave direction finding antenna interface is disclosed which is capable of operating over multioctave bandwidth with an upper frequency limit exceeding forty gigahertz. The antenna, feed circuit/transformer and arithmetic network have non-interrupted TEM electrical paths of strip transmission lines (striplines). Further, a process of fabricating the antenna, feed circuit/transformer and arithmetic network in conjunction with the support means is described.
