“…The two most serious limitations of the DRAs are its low gain and narrow bandwidth. Recently, various configurations of superstrate were used to enhance the gain of DRAs antennas such as dielectric slabs [4], electromagnetic band gap (EBG) structures [5,6], highly-reflective surfaces [7], and most recently, metamaterial superstrate [8,9]. The bandwidth of DRAs is also limited for single mode operation and this bandwidth is not sufficient for high-rate data transmission in wireless communication systems.…”

Abstract-This paper proposes a double negative metamaterial surface as a superstrate for a multilayer cylindrical dielectric resonator antenna (MCDRA). The aim is to achieve a broadband and high gain Electromagnetic Band Gap (EBG) antenna that can be used in harsh propagation areas to satisfy all the requirements for the 60 GHz wireless communications offering a bandwidth of 7 GHz in the unlicensed ISM band (57-65 GHz), permitting to reach data rates of 10 Gbit/s and more. To meet these objectives various techniques are combined. Numerical and experimental results showed satisfactory performances with achievable impedance bandwidth of more than 10.5% (from 58.1 to 64.2 GHz) and a 18 dBi gain, an enhancement of 13 dBi compared to a homogenous DRA without metamaterial superstrate. The proposed antenna exhibits directive and stable radiation pattern in the entire operating band.

“…Since artificial electromagnetic (EM) metamaterials (MTMs) [8][9][10][11][12][13][14][15][16] exhibit properties not commonly encountered in nature, there has been a renewed and actual interest in using the artificial EM MTMs in the design of monopole or dipole antennas [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] antennas, and high-gain or circularly polarized antennas [13][14][15][16]36] over recent years. In general, the monopole or dipole antennas can be classified into three categories according to the operation mechanisms and the loading manners.…”

“…In this way, the miniaturization and band-notch characteristics in an ultrawide operating band can be engineered due to the subwavelength resonance of the loaded elements. The third category is the monopole or dipole antennas built on the left handed (LH) MTM-surface made of periodically arranged LH particles [34,35]. Through this type of loading, the antenna performances are enhanced in terms of not only the radiation behavior but also the impedance matching.…”

“…Frequency notch characteristics can be easily achieved by loading CSRRs and SRRs [28][29][30][31], however, the multiple resonances associated with multifrequency operation are limited and hardly conducted. Radiation performances may be improved by adopting the MTM surfaces [35], however, the bulk medium may complicate the design and implementation. These not well-addressed issues and insufficient strategies make an improved, alternative design that can be easily characterized and experimentally implemented a pressing task.…”

Abstract-The theory and design of a new family of multifrequency monopole antennas by smartly loading a set of complementary metamaterial transmission line (CMTL) unit cells are investigated. The distributed CMTL elements, epsilon negative (ENG) or double negative (DNG) through incorporating additional capacitive gaps, contain a Koch-shaped extended complementary single split ring resonator pair (K-ECSSRRP) etched on the signal strip. The K-ECSSRRP features dual-shunt branches in the equivalent circuit model, rendering a distinguished resonator with dual zeroth-order resonant (ZOR) modes. By smartly controlling the element layout and loading different numbers of unit cells, ten antennas covering different communication standards (GSM1800, UMTS, Bluetooth, DMB and WIMAX) are designed and four of them are fabricated and measured. At most of operating frequencies, the antennas exhibit impedance matching better than −10 dB and normal monopolar radiation patterns. Numerical and experimental results both confirm that the single-cell or dual-cell ENG and DNG CMTL-loaded monopoles exhibit almost identical dual ZOR modes. Moreover, the loaded elements also contribute to the radiation, which is the major advantage of this prescription over previous lumped-element loadings. These antennas are compact and the multiple operating bands can be arbitrarily engineered, enabling an alternative and easy avenue toward monopoles with multifunction and high integration.

“…In fact, the mutual coupling of an array of 2 2 2 dipoles has been reduced in 14 dB with the addition of meta-surfaces [8]. Finally, the frequency selective properties of the meta-surfaces can be exploited for the design of highly-isolated multi-frequency antenna arrays [9], [10]. This antenna concept also presents new opportunities in the design of multi-functional antennas.…”

The design of a multi-functional antenna based on meta-surfaces is investigated. The proposed structure consists of a wideband dipole antenna located between two meta-surfaces working in different frequency bands. The result is an antenna with enhanced gain that radiates in a different half-space at each frequency band. A prototype composed of an elliptical dipole and two meta-surfaces formed by grids of cut and continuous wires demonstrates that the proposed antenna discriminates the radiation in different half-spaces, as well as increases the gain of a nearly omnidirectional dipole to values 8.9 dBi and 7.7 dBi for the top and bottom half-spaces, respectively. Moreover, the antenna remains planar with total thickness of 0 13 at the lowest resonant frequency.Index Terms-Low-profile antenna, meta-surfaces, multi-functional antenna, spatial diversity.
