Abstract :
A technique is described for using the back face of a monolithic chip to realise integrated radiating elements. By using the thin-film microstrip (TFMS) transmission-line medium, electrical isolation between the radiating elements and the front-face circuitry is achieved. Through-GaAs via holes are used to interconnect the radiating elements and the TFMS feed lines. A 35 GHz prototype monolithic antenna has been successfully tested.
