“…As a proof of concept, the focus was given to the first resonances only, and thus, higher order modes were not studied in great detail. Higher order modes of the Sierpinski gasket antennas have been studied in [11] and [12]. However, all of the first resonance frequencies were correctly simulated.…”

“…Several of these designs have been extensively studied, including Koch [7]- [9], Hilbert, Peano, Minkowski, and Sierpinski [10], [11] geometrical shapes or array arrangements [10], demonstrating both compactness and multiband behavior. A comprehensive review [12] describes in detail, among others, the multiband function of the Sierpinski gasket monopole and dipole antennas.…”

Abstract-Devices and systems that use RF microelectromechanical systems (RF MEMS) switching elements typically use one switch topology. The switch is designed to meet all of the performance criteria. However, this can be limiting for highly dynamic applications that require a great deal of reconfigurability. In this paper, three sets of RF MEMS switches with different actuation voltages are used to sequentially activate and deactivate parts of a multiband Sierpinski fractal antenna. The implementation of such a concept allows for direct actuation of the electrostatic MEMS switches through the RF signal feed, therefore eliminating the need for individual switch dc bias lines. This reconfigurable antenna was fabricated on liquid crystal polymer substrate and operates at several different frequencies between 2.4 and 18 GHz while maintaining its radiation characteristics. It is the first integrated RF MEMS reconfigurable antenna on a flexible organic polymer substrate for multiband antenna applications. Simulation and measurement results are presented in this paper to validate the proposed concept.[ 2007-0013]Index Terms-Liquid crystal polymer (LCP), multiband, reconfigurable antenna, RF microelectromechanical systems (RF MEMS), Sierpinski fractal antenna.

“…, At the frequencies in each of the two bands, the values of S 21 are similar to those at f 1 and f 2 , since the curve changes slowly over the bands. Additionally, it is thought that the proposed design can be adopted for dual-band antenna arrays with smaller footprints, as in [11].…”

“…So a single microstrip fractal antenna consists of many self similar antennas, thus forming a microstrip fractal patch antenna. Microstrip antennas with fractal geometry have been found [2,38,40] to have a higher degree of directivity and multiple resonating frequencies. …”

“…Antenna research deals with two core issues-design and its implementation-, to develop multiband smaller size antennas. These fractal shaped designs [38] were used to enhance the existing designs of microstrip antennas, which led to the eventual realization of reconfigurable antennas. Reconfigurable antennas are a specific design of antennas that are used to save power.…”

With the increase in traffic on the internet, there is a greater demand for wireless mobile and ubiquitous applications. These applications need antennas that are not only broadband, but can also work in different frequency spectrums. Even though there is a greater demand for such applications, it is still imperative to conserve power. Thus, there is a need to design multi-broadband antennas that do not use a lot of power. Reconfigurable antennas can work in different frequency spectrums as well as conserve power. The current designs of reconfigurable antennas work only in one band. There is a need to design reconfigurable antennas that work in different frequency spectrums. In this current era of high power consumption there is also a greater demand for wireless powering. This dissertation explores ideal designs of reconfigurable antennas that can improve performance and enable wireless powering. This dissertation also presents lab results of the multi-broadband reconfigurable antenna that was created. A detailed mathematical analyses, as well as extensive simulation results are also presented. The novel reconfigurable antenna designs can be extended to Multiple Input Multiple Output (MIMO) environments and military applications.viii
