Characteristic Mode Analysis of a few Symmetric English Alphabet Shaped Antennas

摘要

This paper presents the Characteristic Mode Analysis (CMA) of antennas resembling some symmetric letters of the English alphabet. The designed structures are analyzed to find out the dominant as well as higher order modes within a selected frequency range (1GHz to 10 GHz). The far-fields of the significant radiating modes are simulated and analyzed for potential use in everyday communication systems. It has been found that apart from possessing acceptable radiation patterns, these structures also cover some IEEE standard wireless communication channels.
