摘要： An antenna system includes an array of notch radiators, arranged in aligned rows on longitudinal axes to define a series of troughs between adjacent notch radiator rows within an aperture area, each notch radiator including a tip region. A plurality of surface/traveling wave suppressors fabricated of microwave energy absorbing material is disposed in the troughs, so that a longest suppressor dimension is transverse or nearly transverse to the array face and so that a suppressor surface is transverse or nearly transverse to the longitudinal axes.

摘要： 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.

摘要： A three port microwave circulator in a slot line transmission medium. Two slot lines are formed which extend from two ports of the circulator in a collinear alignment through a coupler region, and are joined at a power combining junction to provide a single transmission line to the third port of the circulator. A ferrite slab overlays the coupler region. The ferrite is saturated with a static magnetic field, applied by a magnet, along a direction of signal propagation. The circulator can be integrated into a flared notch radiator element to provide separate transmit and receive ports.
