29	MATLAB-Based Dipole Array Simulator Tool For MIT Haystack Observatory Bertulli, Scott 05 May 2005 (has links) The following results were obtained in the presented thesis: 1. Based on a previous work on the MoM method, a software modulus was created and tested in MATLAB, which solves a small-size scanning metal array with arbitrary element position and arbitrary lumped loading. 2. The solver was applied to optimize a broadband planar array of dipoles using the concept of negative lumped loading, which was introduced by R.C. Hansen in 2003. The problem statement was formulated by E. Kratzenberg of MIT Haystack Observatory. 3. The optimization implies full testing of varied array configurations with different element numbers, dipole thicknesses, generator impedances, and lumped loading values. 4. The results obtained indicate that that both 4x4 and 6x6 arrays of dipoles may be optimized over the frequency band from 50 to 300 MHz. The optimization means that the Scan Element Pattern of the array at zenith nearly follows the theoretical limit (area gain per element). antenna dipole phased array active loading Phased array antennas Design
