Development of Novel Phase Shifterless RF Phase Array Antenna Systems

The objective of this proposal is to utilize our advanced technology and design concepts with nonlinear dynamics to develop phase-shifterless RF phase array antenna systems. We plan to use monolithic and fully-integrated novel coupled Voltage-Controlled Oscillator (VCO) arrays to realize small and phase-shifterless efficient phase arrays antennas capable of supporting wideband software-defined radio communication systems. We will demonstrate the prototype operation and feasibility of these monolithic coupled VCO arrays to replace the bulky and expensive phase-shifters commonly used for the current active antenna array systems. We will exploit nonlinear dynamics of the monolithic and mutually coupled VCO arrays for wideband wireless receive (Rx) and transmit (Tx) applications.
