A dual polarized cross notch array employing a positioner for locating and grounding metallized portions of unrestrained element ends with respect to metallized restrained element ends. The positioner is a planar member having spaced rows and slots in intersecting rows and columns. Conductive tabs are formed adjacent to the slots at the intersections of the rows and columns corresponding to intersections of the element ends. The conductive tabs receive corresponding portions of the intersecting element ends in secure mechanical engagement and electrical contact. The positioner maintains the polarized elements rigidly in orthogonal configuration. In alternative embodiment employs conductive members preferably formed of tape at the inside corners of the array. Improved radiator elements and a positioner for preconfiguring the array is also disclosed.

Positioner with corner contacts for cross notch array and improved

A planar dielectric substrate supports a stripline conductor therein. A conductive housing has one or more recesses for receiving a dielectric and a conductive cover is mountable over the dielectric in contact with the housing to enclose the dielectric and isolate the stripline from adjacent structures. The housing and cover have aligned slots disposed on opposite sides of the dielectric and transverse to the stripline for providing coupling of signals between the stripline and the slot. An aperture is formed in the housing in communication with the slot. Other embodiments of the invention include impedance matching means for either or both of the stripline and the aperture for optimizing the efficiency measured in terms of VSWR of the radiator.
