Titel:
Design of Radiating K-Band HEMT Oscillators by Means of Moment Method Approach 
Abstract:
This paper discusses the design of radiating K-band oscillators with high electron-mobility transistors (HEMTs) as active devices. In order to allow monolithic integration, the design Is based on a uniplanar microstrip configuration, i.e., all terminals of the passive microstrip circuit are located on top of the substrate and no via-holes are needed. In this configuration, feeding of the microstrip lines is incompatible to the fundamental quasi-TEM microstrip mode. Moreover, the radiation losses...    »
