In this study, a new configuration of a low profile, broadband printed quasi‐Yagi antenna with two directly fed monopoles has been proposed. The property of a printed monopole antenna with a simple microstrip feed‐line has been used to simplify feeding structure of the printed quasi‐Yagi antenna. A broad bandwidth is achieved by cascading another monopole element of different lengths in a series to obtain two nearby resonances. The proposed antenna consists of two driven monopoles on one side of the dielectric substrate, whereas, on the other side, a reflector and a director are realized as parasitic monopole elements, directly on the ground plane. The measured impedance bandwidth of 70.2% (1.46‐3.05 GHz) with stable gain ranging from 4.7 to 5.3 dBi in the entire bandwidth has been achieved. The antenna has the front‐to‐back ratio better than 10 dB and cross‐polarization level below −20 dB in the direction of maximum radiation over the entire bandwidth. The simulated performance of the antenna has been experimentally verified with good agreement.

Another antenna with metamaterial is designed by Sarkar et al [9], and its size has been reduced 26.67% compared with an ordinary one, but it is a pity that there is little improvement in the bandwidth.

Abstract-This paper presents two novel miniaturized broadband Quasi-Yagi antennas which adopt compact layouts and two different modified bowties as driven dipoles. In these antennas, the microstrip feed and λ/4 impedance transformer are placed horizontally and rearranged in a same horizontal line with balun to reduce the vertical size. The horizontal size is reduced by loading the vertical metallic strips at the sides of bowtie driven dipole and ground patch. Compared with the conventional QuasiYagi antenna, the sizes of the two proposed antennas are decreased to approximately 50%. The experiment results exhibit that they have wide bandwidths of 2.27-3.35 GHz and 2.14-3.3 GHz for reflection coefficient below −10 dB. Their gains reach 4 dBi over the operation frequency band, which indicate that they can be applied conveniently in wireless communications and recognition fields like WLAN, RFID, WiMAX and LTE frequency bands.

Overview of Planar Antenna Loading Metamaterials for Gain Performance Enhancement: The Two Decades of Progress

Metamaterials (MTMs) are artificially engineered materials with unique electromagnetic properties not occurring in natural materials. MTMs have gained considerable attention owing to their exotic electromagnetic characteristics such as negative permittivity and permeability, thereby a negative refraction index. These extraordinary properties enable many practical applications such as super-lenses, and cloaking technology, and are used to design different electromagnetic devices like filters, polarization converters, sensors, and absorbers. Advances in MTMs have made new application fields to emerge in communication subsystems, especially in the field of antennas. MTMs are usually arranged in front or above the radiating element, or incorporated in the same substrate to improve the performance of planar antennas, in terms of improving directivity, gain, bandwidth, and efficiency, reducing the size and mutual coupling, and deflecting the radiation characteristics. High gain antennas are demanded in modern wireless communication systems. Their importance is in improving the signal strength by reducing the interference and alleviating the free space path loss. This review paper provides a brief introduction to MTMs, with the focus on their operating principles. Furthermore, a detailed study of antenna gain enhancement based on the various properties of MTMs is carried out. MTMs with low values of constitutive parameters; zero-index material (ZIM), lowindex material (LIM), epsilon-near-zero (ENZ), and mu-near-zero (MNZ) are discussed in detail in the context of their capability to enhance the gain of a broad class of planar antennas. The low impedance property and lensing property, which is achieved by three different characteristics: high refractive index (HRI), gradient refractive index (GRIN), and negative refractive index (NRI) materials, are loaded to planar antennas for gain enhancement. The scope of this review has been limited to antennas that were experimentally validated in the respective source papers.INDEX TERMS Metamaterials (MTMs), gain enhancement, low impedance MTM, MTM lens, planar antennas, ZIM.
