Circuit architectures for a differentially segmented aperture antenna

Abstract

In an approach to a system for a differentially segmented aperture (DSA) antenna includes protrusions arranged in an array, and pixels formed in an array, each pixel formed between two adjacent protrusions; and one or more signal chains, each including: transmit circuitry comprising digital-to-analog circuitry to generate an analog signal at a selected operating frequency based on a transmit digital signal representing the first analog signal to be transmitted to a target; receive circuitry comprising analog-to-digital circuitry to receive a second analog signal at the plurality of pixels of the DSA antenna, and to generate a receive digital signal representing the second analog signal; and pixel combiner circuitry to receive the first analog signal and control the pixels of the array with the first analog signal, and to receive analog signals from the pixels of the array and combine the analog signals to form an array analog receive signal.
