Sparse Cantor Ring Antenna Arrays with Non- Uniform Element Spacing
This research project is based on previous work done by Dwight L. Jaggard and Aaron D. Jaggard on fractal ring arrays. We utilize fractals in the fabrication of a class of Cantor ring arrays. Fractal descriptors such as dimension, stage of growth, and lacunarity are applied in designing and characterizing these Cantor rings. Using the continuous arrays developed by Jaggard and Jaggard as a poin...
متن کاملPattern Correlation and Mismatch in Two-element Antenna Arrays
In an antenna array the element pattern correlation and the array matching depend on each other. For lossless two-element arrays the general formulation of the dependency of array matching on pattern correlation is given and solved numerically for some basic cases. Array matching is given as a characteristic mismatch coefficient and as the mean relative reflected power.
متن کاملFractal Antenna Arrays Nsf
This research involves the overlaps of antenna theory, fractal geometry, and numerical calculations. Its goal is to investigate how random or periodic antenna array geometry can be improved through the use of fractals. Using a program we developed in Matlab, we plotted the radiation of linear/planar antenna arrays. We were able to correctly analyze radiation of three two-dimensional arrays. Ano...
متن کاملVirtual Antenna Arrays
The ubiquitous trend to “go wireless” is a symbol of our need for independence and flexibility. To allow for such an “all-wireless” world, large amounts of information with widely varying content have to be exchanged, utilising a limited wireless spectrum. Wireless capacity is thus the keyword and research concentrates on an efficient utilisation of the available frequency spectrum. Recently, i...
متن کاملUtilizing Adaptive Antenna Arrays
PERFORMANCE IMPROVEMENTS IN WIRELESS CDMA COMMUNICATIONS UTILIZING ADAPTIVE ANTENNA ARRAYS by Weichen Ye This dissertation studies applications of adaptive antenna arrays and spacetime adaptive processing (STAP) in wireless code-division multiple-access (('D11 A) communications. The work addresses three aspects of the CDMA communications problems: (I) near-far resistance, (2) reverse link, (3) ...
