Direct-Signal Modulation Using a Silicon Microstrip Patch Antenna

Vincent F. Fusco, Senior Member, IEEE and Qiang Chen, Member, IEEE

Page 1025.

Abstract:

In this paper, a microstrip patch antenna is fabricated directly onto a high-resistivity silicon substrate without an insulating barrier, thereby forming a distributed Schottky diode between the patch radiator metallization and ground plane. By applying dc bias control to the patch metallization, direct amplitude modulation of a CW microwave carrier can be achieved. Experimental results are presented that show the far-field radiation characteristics of the structure and its response to applied base-band modulation signals. Also direct base-band signal detection using the patch antenna is discussed.
