Microprocessor controlled microstrip phased array
Abstract
In this paper, two advancements in state-of-the-art, microstrip antenna technology are presented. First, a totally monolithic microstrip phased array for C-Band operation (5 GHz) was produced. The array is capable of beam steering in two planes, is conformal and low profile. All radiating elements, phase shifters, power dividers, RF chokes, and dc bias lines are etched on one side of a teflon fiberglass circuit board. The array is composed of 16 linearly polarized, quarter-wavelength microstrip radiating elements in a 4 x 4 configuration. The second advancement in technology was the development of a microprocessor controller to provide the necessary beam steering commands. This controller is used to calculate the phase shift settings required at each element to scan the beam to a predetermined angle.
