Design of beam-forming networks for scannable multi-beam antenna arrays using CORPS

This paper deals with the design of beam-forming networks (BFN) for scannable multibeam antenna arrays using Coherently Radiating Periodic Structures (CORPS). This design of CORPS-BFN considers the optimization of the complex inputs of the feeding network by using the Differential Evolution (DE) algorithm. Simulation results for different configurations of CORPS-BFN for a scannable multibeam linear array are presented. The results shown in this paper present certain interesting characteristics in the array factor response for the scannable multibeam linear array and the feeding network simplification for the design of BFN based on CORPS.This work was supported by the Mexican National Science and Technology Council, CONACyT, under grant J50839-Y and the Science and Technology Council of Tamaulipas Mexico (COTACyT) under Grant 2007-C13-73901

Simplifying the feeding network for multi-beam circular antenna arrays by using corps

An innovative way to analyze the design of beam-forming networks (BFN) for scannable multi-beam circular antenna arrays using the CORPS (Coherently Radiating Periodic Structures) concept is introduced. This design of CORPS-BFN considers the optimization of the complex inputs of the feeding network by using the Differential Evolution (DE) method. Simulation results for different configurations of CORPS-BFN for a scannable circular array are presented. The results shown in this paper illustrate certain interesting characteristics in the behavior of the array factor for the scannable circular array. The most significant aspect that is unique to this proposal is the simplification of the feeding network based on CORPS.This work was supported by the Mexican National Science and Technology Council, CONACyT, under grant 127919 and the Science and Technology Council of Tamaulipas Mexico COTACyT under grant 2007-C13-73901 and 108166
