New Phased Array designs allow electronic radar beam forming and low cost production for military and industry
In his PhD thesis, Danial Ehayaie presents three new approaches to the design of phased array antennas in order to reduce their complexity. First approach based on extended resonance technique achieving power dividing and phase shifting within a single circuit. In the 2nd approach, the author applies a bi-directional feeding method. This approach demands less phase shift from phase shifters as needed in traditional phased array applications. In the 3rd approach, the author achieves a variable phase shift through a vector summation of signals. This allows phase progression across the antenna elements through one single phase shifter.
In times where dynamic beams are required in many new military and industrial applications, these inventions promise cost reduction and easier, scalable and miniaturized production processes.
