Slot antennas on GaAs for integrated array applications

Slot antennas are proposed for integration into GaAs monolithic phased arrays. The characteristics of suitable slot radiators are discussed and a technique for measuring the input impedance is described. Examples in the 20 to 30 GHz range show that the geometry of the slot may be varied to obtain input impedances which allow matching to either active MMIC devices or to a 50 Ω system.
