Fractal 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) ...
متن کامل1 Antennas and Antenna Arrays
Antennas have become ubiquitous devices and occupy a salient position in wireless systems. Radio and TV as well as satellite and new generation mobile communications have experienced the largest growth among industry systems. The global wireless market continues to grow at breakneck speed and the strongest economic and social impact nowadays comes from cellular telephony, personal communication...
متن کاملFractal Antenna Elements and Arrays
With the advance of wireless communication systems and increasing importance of other wireless applications, wideband and low profile antennas are in great demand for both commercial and military applications. Multi-band and wideband antennas are desirable in personal communication systems, small satellite communication terminals, and other wireless applications. Wideband antennas also find app...
