“…So different techniques have been proposed to enhance the gain as per the requirement. For ease of classification, the available literature is divided into two categories: only gain improvement and simultaneous gain and bandwidth improvement . The categories are described here.…”

“…As per literature, the DR‐antenna shape has much impact on controlling the far‐field gain. First, the shape of the DR has been found to be playing crucial role in enhancing the antenna gain. Next, multiple stacking generates more radiation from side walls of the DR than top side enabling high gain in end‐fire direction.…”

“…Recently, a conformal frequency selective surface (FSS) has been placed vertically on side of a DRA as a reflector to reach a peak gain of 9.5 dBi. Coulibaly et al have proposed an antenna composed of a superstrate, an aperture coupled feed, an intermediate substrate and a cylindrical dielectric resonator for achieving a bandwidth of 18.4% at the centered frequency of 59.83 GHz and a gain of 11 dB over the entire ISM bandwidth.…”

This article outlines a compressive review on investigation carried out targeting to gain, circular polarization (CP), and mutual coupling reduction in dielectric resonator antenna (DRA). The DRA has already been created a separate position in antenna engineering domain because of its adept characteristics, such as wide bandwidth, high efficiency, low‐loss, and mainly 3D‐design flexibility which is rarely available in conventional antennas. In this context, the research on gain, circular polarization, and mutual coupling are quite interesting and being carried out from the last two decades. The ultimate aim of this article is to (i) give an overview of different techniques adopted in context to gain, CP, and mutual coupling reduction; (ii) give a compressive review of notable research carried out targeting to these three characteristics; and (iii) find out the research gap concentration for furtherance of the same.

“…Metallic reflectors can be used below the antenna for the purpose, however as the spacing between antenna and the reflector is fixed, this kind of arrangement is not capable of producing enhanced radiation over a wide bandwidth. To overcome these problems periodic structures like Partially Reflective Surfaces (PRS) and Frequency Selective Surfaces (FSS) are being used nowadays in place of solid metallic reflectors [14][15][16][17][18]. Alexandros P. Feresidis et al proposed a FSS-based Artificial Magnetic Conductor (AMC) operating at 22 GHz placed surrounding a patch antenna [14].…”

In this paper, a frequency selective surface (FSS) with tunable bandstop performance by integrating graphene is discussed. The graphene implanted in the circular FSS unit makes the transmission and reflection bands of the proposed FSS tunable owing to its alterable complex conductivity controlled by the chemical potential. The transmission zero of the proposed FSS performing as a reflection plane happens at the frequency from 1.65 THz to 2.19 THz when the chemical potentials of graphene change from 0 eV to 1 eV. Moreover, reconfigurable radiation pattern of a traditional dipole antenna is accomplished loaded with the proposed FSS by altering the complex conductivity of graphene. The dipole has a directional radiation pattern with enhanced directivity at 2.1 THz by adding the proposed FSS with μc = 0.8 eV. However, the omnidirectional radiation pattern is maintained by changing the value of chemical potential to 0 eV while the FSS is nearly transparent. Therefore, a radiation diversity property could be achieved by controlling the chemical potential of graphene loaded in FSS.
