Abstract:

An array of thick flared notch radiators, wherein the separation distance between adjacent pairs of flared notch sticks is set to be less than one-half wavelength at the highest frequency of concern. The separation distance suppresses the propagation of higher order modes along the length of the sticks, which would degrade the array performance. The separation distance is achieved by fabricating the sticks with an increased thickness, thereby reducing the stick-to-stick channel width.
