Nested cavity embedded loop mode antenna

(Canceled)

A method of providing an ultra wide band antenna having a loop type antenna pattern over the bands of operation of the antenna, comprising the steps of:

• nesting a number of cavity embedded meander line loaded antenna modules having different non-overlapping frequency bands of operation, each of said modules having an outer conductive cavity, and further including a ground plane plate above said cavities, a meander line at the top of said outer conductive cavity having an end coupled to said cavity, and means for coupling an end of said meander line to said ground plane plate;
• and,
• providing the antenna modules with a common feed, whereby any side lobes are minimized such that there is no significant null in a direction perpendicular to the face of the nested modules.

A compact flush-mountable ultra wide band antenna, comprising:

• a number of nested cavity embedded meander line loaded antenna modules, each of said modules having an electrically conductive cavity having a top periphery, an apertured dielectric layer at said top periphery, at least one meander line on said dielectric layer and having an end electrically connected to said cavity, a ground plane plate above said meander line and a coupler for coupling another portion of said meander line to said ground plane plate, the aperture in said dielectric layer being of a size to permit the insertion of a smaller cavity therethrough to permit said nesting;
• and,
• a common feed for said antenna modules, said modules having substantially non-overlapping bands of operation.
