18 November 1989Optically Controlled Millimeter Wave Phased Array Antennas.
This paper is concerned with recent developments related to optically controlled phased array antennas operating in the millimeter wave range. The antenna consists of three main elements: the central processing unit (CPU), the fiberoptic (FO) distribution system with optical signal processing capability, and the planar array. The antenna array is composed of a large number of distributed and independently powered transmit/receive (T/R) modules fabricated by monolithic microwave integrated circuit (MMIC) techniques. The function of the fiber optic distribution system is to distribute the carrier reference signals for the frequency synchronization of the T/R modules, to transmit the appropriate control signals for beam forming, and to route the information and data signals.
