Finite Element Modeling of Minkowski Monopole Antennas Printed on Wireless Devices

摘要

A novel monopole antenna element printed on the circuit board of a wireless device is presented. Following the Minkowski fractal curve along with folding techniques, the proposed element is an electrically small self-resonant antenna with high efficiency and wide bandwidth. Due to its miniature size, it can be used in dual antenna portable devices operating in the 2.4 GHz band, in order to achieve antenna diversity under all combining schemes. The performance of the investigated configurations was predicted through finite element simulations, which proved to be computationally more demanding than their moment method counterparts.
