Effect of Metamaterial Cells Array on a Microstrip Patch Antenna Design

Abstract

In this paper, a microstrip patch antenna (MPA) design was developed to verify the performance of a metamaterial cell array (MTM) Capacitive Loaded Loop (CLL) immersed in the substrate. The metamaterial was obtained from metal laminates designed inside a dielectric material, with dimensions carefully calculated to have the effective negative permittivity and permeability, consequently the negative refractive index, in a certain frequency range. In this case, the geometric control of the unit cell parameters allowed its organization in a periodic arrangement to be immersed in the MPA substrate. Simulated and experimental results were obtained and compared for some parameters of the antenna, which showed a good relationship between MTM and MPA performance.

“…Highly efficient polarization reflection of this metasurface helps to energy gathering that increases the gain. An array of metamaterial unit cells are used with an antenna to increase the bandwidth 20 . Moreover, several metamaterial structures have been described in the literature 21 – 23 with effective parameter analysis, and these metamaterials can be used with microwave devices.…”

Angularly stable frequency selective surface for the gain enhancement of isolated multiple input multiple output antenna

“…Several approaches have been reported to enhance the gain of microstrip antenna, such are antenna with defected ground structure (DGS), 5 substrate, 6 superstrate, [7][8][9] reflective surface, [10][11][12][13][14] and metamaterial. 15,16 In the Reference 5, multiple input multiple output (MIMO) antenna with a DGS structure was designed to improve the gain of an antenna. However, the antenna with DGS or with slots in the ground affects the radiation pattern which is important to be considered.…”

“…In recent years, to improve the performance of the antenna, additional periodic structures in the form of substrates or superstrates have been loaded above the antenna or below the antenna. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] In the References 15,16, the metamaterial structure was designed and loaded to the antenna to improve its performance. However the performance in terms of gain, directivity was improved but the metamaterial structure has some additional losses due to the insertion of metal laminates in its structure.…”
