Highly Miniaturized Fractal Antennas

Abstract

In this paper, the use of fractal elements in miniaturized antenna applications is discussed. Hilbert grounded wires are studied and a simple design routine is outlined. Using commercial software tools, the design of groundless fractals is shown to be simple and fast. We present grounded and groundless Hilbert and Meander antennas for 250 MHz, 400 MHz and 2 GHz applications. Application of Hubert antennas in GSM/PCS bands is also presented
