“…Antenna behavior and far field radiation patterns could be predicted with the known and available knowledge of DR's resonant modes [25]. Numerous geometries of DRA's are available which include cylindrical, rectangular, half-cylindrical, spherical, triangular and hexagonal [29][30][31][32][33].…”

“…The antenna is excited via the 50 silver nanostrip feed that has a width of Wf = 0.067 ȝm and optimized length of Lf = 1.86 ȝm.In order to control the matching at the central frequency of 193.5 THz and to achieve a wide bandwidth with acceptable radiation patterns a small same substrate material with thickness h3 = 0.015 ȝm has been introduced between the equilateral triangle and the nanostrip. The dimensions of equilateral triangular dielectric are calculated from equation (1)[32].…”

To fulfill the growing demands of high data rate communication, researchers are now focusing their concentration on the higher frequency bands lying in the THz region of the electromagnetic spectrum. With the advent of nano-components fabrication technology, researchers and scientists are now able to fabricate optical antennas at a nano-scale, in order to establishing a wireless commination link at THz frequencies, and find solutions to the general design problems associated with higher frequency antennas. Drawing inspiration from antennas at microwaves and radio-frequency technologies, optical antennas capture and couple free available electromagnetic radiation in the visible and infrared wavelengths in the same way as radio electric antennas do at the corresponding wavelengths. In this paper, authors review some of the state of the art optical antennas, their fabrication techniques and propose a novel dielectric nano antenna design. Comparing to the traditional radio-frequency antennas, an equilateral triangular dielectric resonator nano-antenna (ETDRNA) has been designed and simulated at 193.5 THz standard optical frequency. The proposed antenna is a planar structure having a multilayer geometry consisting of 'Ag' partial ground plane, a top and bottom 'SiO2' substrate and a 'Si' equilateral triangular as a dielectric fed by a 'Ag' nanostrip transmission line. The simulated antenna achieves an impedance bandwidth of 2.58% (192.5-197.3 THz) and an end-fire directivity of 8.6 dBi, covering all of the standard optical transmission window at C-band. Numerical demonstrations prove the efficiency of the nano-antenna at the frequencies of interest, making it a viable candidate for electromagnetic communication in optical applications and nanonetworks.

“…The advantage of the triangular DRA is that for a given height and resonant frequency, it offers a smaller area than either a cylindrical or rectangular DRA [18,19]. Thus, it is advantageous for an antenna array design since a larger range of spacing between elements is allowed.…”

Abstract-A wideband dual segment three element triangular dielectric resonator antenna (TDRA) has been proposed for applications in X-band. Proposed antenna has been fabricated and tested. The simulation study of the antenna is carried out using Ansoft HFSS simulation software. The simulation results for input characteristics and radiation patterns of the proposed antenna are compared with corresponding experimental results at the resonant frequency. The simulation results are in agreement with the measurement results. The return loss-frequency characteristics of the proposed antenna are also compared with those of single element, and three element TDRAs.

Abstract-An analytical solution for the radiation by a prolate hemispheroidal dielectric resonator antenna (DRA) over an infinite ground plane excited by a rectangular slot is presented. The dyadic Green's functions pertaining to a magnetic-current source are used in a form convenient for numerical computations. The dyadic Green's functions are then employed to formulate the electromagnetic fields radiated by the DRA. The electromagnetic far field is expressed analytically in a compact form. The far field patterns for different design parameters are computed and plotted.
