摘要： 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.

摘要： A planar, phased-array antenna including a nonconductive substantially planar substrate and a transmission line disposed on one surface is disclosed, a segment of the transmission line forming an arc of radius R centered on the antenna axis. A conductive layer on the other antenna surface includes two or more slotted openings, each slotted opening having one end located within a distance R of the antenna axis, such that, when an electromagnetic signal is fed into one end of the transmission line, electromagnetic energy is sequentially coupled into the slotted openings, and a circularly-polarized signal is radiated from the antenna substantially in the direction of the antenna axis. An amplifier or a connector may be electrically connected to one or both ends of the transmission line, or one end of the transmission line may be terminated in an impedance load to form a leaky-wave antenna. The slotted openings may comprise either or both straight and curved segments, and may be of the same or unequal lengths. Curved slotted openings may be oriented clockwise or counter-clockwise to transmit or receive either is left-handed or right-handed polarized signals.

摘要： Apparatus using a global positioning system (GPS) for finding out the attitude of a rotating space vehicle employs first and second antennae mounted opposite from each other on a circumference of the body of the rotating space vehicle. The antennae receive GPS satellite signals in their channels. A control and tracking loop processor monitors the signal strength in each channel. Phase errors produced by phase discriminators of each channel arc combined to produce a spin signature which is used to calculate the vehicle spin rate and vehicle attitude.
