Abstract (en)
[origin: US5148182A] The present invention provides phased arrays using monolithic technology of diffusions over whole wafers for working in millimetric wave frequency bands. The reflector array includes a plurality of metallizations connected together by diodes whose capacity can be varied. Thus direct control of reactive impedances is obtained. With the metallized strips placed at a distance substantially equal to lambda /4 from a ground plane, it is possible to control locally the phase of the reflected signal.
