“…For a more complete pattern analysis, the total field which includes the co-and cross-polarizations of the radiation should be taken into account. The time domain performance such as the group delay and impulse response should also be examined (Chen et al, 2004). Recently, several monopoles have been proposed for various UWB applications.…”

“…One of the challenging research objectives is to propose miniaturized, cost-effective antennas with power radiation uniformly in all transmission directions, ultrahigh bandwidth, and nondispersive behavior for UWB communication systems [5]. The antenna model is also critical since it has a major impact on the complexity and size of the receiver and transmitter designs for portable devices [6].…”

Abstract:A modified hexagonal Sierpinski gasket-based fractal antenna is proposed for ultrawide-band (UWB) wireless applications. The designed antenna has miniaturized (36 × 48 mm 2 ) and multiband characteristics. Two design guidelines, the partial ground plane technique and the circular annular ring patch on the substrate, are applied to improve impedance matching and radiation pattern characteristics. According to the simulation results, the proposed modified antenna has a reflection coefficient S11 of less than -15 dB, a linear phase of the reflection coefficient, 80% radiation efficiency, 2-4.5 dBi antenna gain, and omnidirectional radiation pattern properties over the full UWB spectrum (3.1-10.6 GHz). Simulated results obtained for this antenna show the expected good radiation behavior within the full 7.5-GHz UWB bandwidth.

“…The primary challenge is how to characterize the antenna system effectively. The concept of transfer function [1][2][3] leads to a proper understanding of a UWB antenna system. However, to determine the transfer function over an ultra-wide band entails expensive computational cost.…”

Abstract-This paper proposes an efficient and automatic means of achieving a reduced model of a transfer function for UWB antenna design. According to the formulation of a transfer function, we have derived two factors, which are critical in determining the radiation pattern and input impedance respectively. Their special formula allow us to establish a reduced model automatically using the Model Order Reduction (MOR) techniques of a second order system. The process is free of any human factors and suitable to any antenna systems, thus enabling a direct and efficient interface with the optimization process in the design of a UWB antenna system. In addition, the proposed way of establishing a transfer function of the whole antenna system has successfully cascaded the entire system into separate subsystems, thus offering deeper insights in analyzing a UWB antenna system.
