The metamaterial elements and structures have been noticed for obtaining circular polarization (CP) while developing various procedures. In this paper, we have mentioned some of these cases and compared the metamaterial loads effect on antenna current distribution. We have classified them into four categories. The first case covers patch antenna based on composite right/left‐handed method, where the metamaterial has been used for changing the current distribution in the loop form. The second case has been achieved by radome and metasurface. In the third model, the interaction between feed and metamaterial load has been considered and the last case has been made by the metamaterial load with truncated structure. The metamaterial loading has been modeled based on Nicolson‐Ross or transmission/reflection techniques for extracting the permittivity and permeability. While the microstrip slot antennas are attractive for wider bandwidth, the truncated structure can change the current for achieving CP. Here, we have studied the antenna for wireless and WiMAX applications.

“…The principle of designing a CP antenna is the two required orthogonal resonant modes with 90‐phase difference and equal amplitude . Due to the benefits of light weight, relative plain structure, broad band impedance bandwidth, good radiation efficiency and eliminate of frequency interference, multiband monopole antennas have been engrossed many antenna designers’ attentions. Hitherto, variants of multiband monopole antenna capable of producing CP have also been recommended.…”

This article presents a novel compact size (20 mm × 16 mm × 0.8 mm) Tai‐chi‐shaped antenna for wireless applications. Dual frequency operation (3.14–4.58 GHz and 4.97–6.53 GHz) is achieved by optimizing the antenna during designing steps. The antenna gives circulary polarization from 3.26 to 4.42 GHz and from 5.45 to 6.63 GHz frequency ranges. The 4.2 dBic stable gain is another evident advantage of proposed work.

A metasurface-based low-profile crossed dipole antenna with wide circularly polarized bandwidth for 2.45 GHz ISM band wireless communications is proposed and fabricated in this article. Consisting of four slit-loaded rectangular patches, the double-sided printing crossed dipoles are fed by a pair of vacant-quarter printed rings which circularly polarized (CP) radiation could be generated. With slits loaded, by properly combining the fundamental mode of the two inverted L-shaped dipole, the slot mode and extra resonance generated by the AMC surface, a wideband circularly polarized operation can be obtained. After optimization, the final design with an overall size of 0.44k 0 3 0.44k 0 3 0.1448k 0 at 2.4 GHz had measured a 31.6% (2-2.75 GHz) impedance bandwidth and 3 dB axial ratio bandwidths of measured were 23.2% (2.1-2.65 GHz), respectively. In addition, the antenna performed a small gain variation (7.0-7.5 dBic) and a front-to-back ratio (FBR) of over 25 dB across the whole CP region.

When two degenerate modes of equal amplitude and phase difference of 908 were excited, a circular polarization (CP) could be achieved. 1 To achieve CP radiation, several printed monopoles have been proposed.2-11 LP and CP operations were achieved by a multiband coplanar monopole antenna with the trapezoidal structure adopted in ref. Recently, with intensely studied in metamaterials (MTMs), the performance of the traditional CP patch antenna has been improved by utilized MTMs. Improvements of enhancements in bandwidth and an overall reduction in size were included. For an overall size of 0.77k 0 3 0.77k 0 3 0.06k 0 , a 3 dB AR bandwidth of 15% was achieved by a diagonal slot-loaded square patch over a 458-oriented reactive impedance surface (RIS).14 An artificial ground structure was applied in a truncated corner square patch in ref. 15, where an AR bandwidth of 20.4% and an overall size of 0.78 k 0 3 0.80 k 0 3 0.096 k 0 has been achieved. To achieve an overall size of <0.3 k 0 3 0.3 k 0 3 0.03 k 0 , MTMs-based single-feed CP patch antennas [16][17][18][19] have been implemented, but narrow 3-dB AR bandwidths (only 5% or less) were exhibited. In refs. 16,20,21, it proposed an AMC and has since been widely applied. Then, a wide CP operation were obtained, but significantly radiation performances and enhancing the bandwidth of and the size of an antenna could be both reduced by applying such surfaces.Int J RF Microw Comput Aided Eng. 2018;28:e21173.
