The dielectric resonator antenna technologies are applicable to design various band level or various types of simulation with low return loss of antenna design. In this paper we have taken several aspect ion of antenna results which has been investigated. The Research Article Concentrated on optical DRA Antenna and performance simulation result is improved with some configurable improvement. The wireless communication system has mainly demanding requirements to improve return loss. Antenna made up of materials has abled to improve its potential performance with high level enhancement. Although most of the optical antenna use 5 nm or less than 5 nm diameters because carbon nanotube become superior conductor at 5 nm diameters. Optical antenna is substitute of traditional antenna or generate model antenna. Which include light – matter interaction, absorption & emission of light which can control its special direction as well as control of its complex non analytic algorithms they behave like strong coupled light emitting devices like photovoltaic.
