ABSTRACT:
The antenna comprises an open-mouthed cylindrical cavity 1 defined by side 11 and bottom 12 walls. A conductive coating 5 on an insulative substrate 4 lies on the bottom wall 12. The coating 5 is spaced from the side wall 11 by an annular space 2. A coaxial line 7, 8 feeds microwave energy to the zone between the coating 5 and the wall 12. That zone acts as a radial transmission line which couples the coaxial line to the cavity.
