Abstract :
There has been a significant effort to develop millimeter-wave active-array antennas for communications and radar applications. A dielectric waveguide is a promising medium for this application. However, the integration of active devices, transmission media, and antennas has been difficult to achieve. This paper presents the first successful demonstration of a phase locked array of millimeter wave grating surface emitters (MMWGSE). We discuss three aspects of MMWGSE: (1) The achievement of an optically steered millimeter wave grating surface emitter. (2) The demonstration of a frequency locked array of millimeter wave grating surface emitters. (3) Rigorous analytical studies of efficiently coupling power from a millimeter wave semiconductor device, to a waveguide which incorporates grating surface emitters. This work leads to a full monolithic array using pseudomorphic high electron mobility transistor (PHEMT)-devices
