“…The parasitic elements induce changes in the current path; due to this, resonance occurs at lower frequencies without increasing the antenna size, thereby providing multiband operation. Multiband operation is achieved by parasitic elements in Reference and in Reference using the ½ λ dipole technique. Inverted L‐shaped and T‐shaped parasitic elements are shown in Figures A and B, respectively.…”

In recent years, the demand for multifunctional components has increased tremendously. Advancement in integrated technology has provided researchers with ample capability to fit diversified applications operating at different frequencies in one wireless device. Integration of multiband antennas in conjunction with frequency reconfigurability offers an optimal antenna design. In addition, the incorporation of metamaterials yields controllable and promising radiation properties. This paper contributes uniquely to the field of antenna design in two ways. First, it provides the domain and technical aspects associated with multiband, frequency reconfigurable, and metamaterial antennas. Second, it provides a critical review of literature. The paper additionally highlights the deficiencies in the design techniques reported in the literature.

“…20 The combination of parasitic element and common ground was designed for multiband WiMAX and WLAN applications earlier. 21 Also, a wideband MIMO antenna with two radiators was designed for mobile devices for LTE, WLAN, WiMAX, WCDMA, and UWB applications. 22 Sometimes miniaturization in MIMO antenna has been achieved by partial disconnected ground.…”

A four‐port multiple input multiple‐output (MIMO) antenna with common radiating element is proposed for 2.4 GHz Wi‐Fi applications. It comprises a modified circular radiator fed by four identical modified feedlines, partial ground planes, and a diagonal parasitic element (DPE). The parasitic element is used to enhance the interport isolation. The antenna has a 2:1 Voltage standing wave ratio (VSWR) impedance band 2.34‐2.56 GHz and nearly omnidirectional radiation patterns. The radiation efficiency is more than 79% and gain is 2 dBi at resonant 2.43 GHz. The isolation in the given frequency band is 10 dB. At the 2.43 GHz, the isolation between adjacent ports (1, 2 and 1, 4) is 14 dB and between opposite ports (1, 3) is 12 dB. The mean effective gain (MEG) ≤ −2.7 dB and envelope correlation coefficient is <0.01. The −10 dB total active reflection coefficient bandwidth is 202 MHz. The antenna is designed for a Wi‐Fi device and the effectiveness of antenna has been checked for distance of ½ feet from the human head. The specific absorption rate (SAR) is found to be ≤0.17 W/Kg by CST simulation tool.

A very compact AMC structure based on a magneto-dielectric substrate is proposed in this paper. A lowprofile spiral loop is inserted under a conventional AMC structure to act as a high permittivity/permeability substrate, which leads to a compact AMC plane. A 75-percent reduction was achieved by this technique compared to the conventional AMC. The modified AMC ground plane is inserted between a human's body and a simple CPW antenna. The specific absorption rate calculation from full wave analyzer shows that a 45-percent reduction is attained compared to the antenna without AMC ground plane. To validate the magneto-dielectric AMC structure, two full wave analyzers were used. The comparison between the two simulators shows a good agreement between them.
