Abstract
The tubular slot-mode antenna includes an array of slot antenna units carried by a tubular substrate, e.g. a cylindrical substrate, and each slot antenna unit having a pair of patch antenna elements arranged in laterally spaced apart relation about at least one central feed position. Adjacent patch antenna elements of adjacent slot-mode antenna units have respective spaced apart edge portions with predetermined shapes and relative positioning to provide increased capacitive coupling therebetween. The array of slot-mode antenna units may define a plurality of ring-shaped slots coaxial with an axis of the tubular substrate, and a feed arrangement may be coupled thereto to operate the array of slot-mode antenna units in an endfire mode.
