“…This research work aims to increase the gain and directivity of the CMPA. In the literature, many microwave engineers have presented their own MM and showed their effect on antenna performance . Although many articles have been published for applying MMs with MPA, there is still a need for MM structures with a high effect on antenna gain and directivity for wider frequency bandwidths depending on the application used.…”

In this study, a novel double‐negative compact metamaterial (MM) that can operate in Ku‐band (12 GHz) is designed and fabricated. It is shown that the proposed structure can be used as a MM for a wide bandwidth of 6 GHz. A double electromagnetic lens layer is then formed using this MM unit cell in an array. Afterwards, obtained lens layers are used together with a conventional microstrip patch antenna (CMPA) operating at 12 GHz. The effect of the MM on the antenna gain and directivity is examined. The CMPA and MMs are fabricated, and measurements are performed in Akdeniz University Microwave Laboratory and simulated with Microwave Studio by Computer Simulation Technology. 71% and 50% improvement in antenna gain and directivity are obtained by using it as a double MM lens layer.

“…If electromagnetic waves can be focused instead of omnidirectional transmission, then the directivity and thus the * Correspondence: bilal1334@gmail.com.tr gain can be increased [2]. Therefore, in order to improve antenna gain and directivity, MM structures are used on antenna substrates [3,4], or on direct antenna geometry [5,6] or as lenses [7,8].…”

This paper proposes improving the directivity of microstrip patch antennas (MPAs) by using metamaterials.Four different metamaterial types are used as a flat lens in front of the MPA, respectively, which are tuned to 12 GHz (Ku-band) resonance frequency. Thus, it can be decided which metamaterial is more proper for antenna directivity enhancement at this band. One additional new metamaterial structure is proposed in this paper, which is called a Euro-shaped resonator, and other metamaterials used are the triangular split ring resonator, symmetrical ring structure, and split ring resonator. The permeability and permittivity of metamaterials are extracted from the S parameters by using a robust method. Microwave Studio by Computer Simulation Technology is used for modeling and simulation.The MPA and metamaterials are fabricated, and measurements are performed in the Yıldız Technical University RF and Microwave Laboratory. It is observed that measured results are in close agreement with the computer simulations.

In this paper a metamaterial-embedded, compact microstrip-fed patch antenna is introduced for microwave C-band applications. The proposed antenna is composed of a rectangular metamaterial-embedded patch, microstrip-fed line and a partial ground plane. The finite-integration technique (FIT) based on Computer Simulation Technology (CST) Microwave Studio is utilized in this study. The measurements of antenna performances are conducted in a near-field measurement laboratory. The antenna performance parameters comprising the reflection coefficient, radiation efficiency, gain, and radiation pattern are studied to validate the antenna performance. The measured results show that the proposed metamaterial-embedded antenna exhibits a wide impedance bandwidth over the C band (from 3.77 GHz to 6.58 GHz). The results also indicate good radiation efficiency and antenna gain with a nearly omni-directional radiation pattern at the frequencies of interest.
