Abstract

A slot-array antenna includes a nonconductive substantially planar substrate and a transmission line disposed on a rear substrate surface where one end of the transmission line is connected to an amplifier, a connector, or an impedance load. A conductive layer on the front substrate surface includes a plurality of slotted openings arrayed about an antenna axis. A surface-wave suppression region encloses the array of slotted openings and a plurality of peripheral openings are disposed between the surface-wave suppression region and the peripheral edge of the antenna.
