A Modified Ultra Wide Band Antenna With Metamaterial Patterns for Telecommunications Systems

摘要

W artykule zaprezentowano projekt ultra szerokopasmowej anteny z periodyczną strukturą w celu optymalizacji wzmocnienia, pasma I rezonansu. Testowano trzy topologie - para krzyży Jeruzalem, struktura fraktalna I układ trzy biegunowy.%In this work, an ultra wide band antenna is modified with periodic structures in order to improve its performance, in terms of gain, bandwidth and resonance. Basically, three topologies are used (Jerusalem cross pair, fractal and tripolar array).The main idea is improve its performance without increase its dimensions which could compromise their application in telecommunications systems especially mobile devices.
