Summary:
Recent developments in nano-technology have jumped from well established radiowave concept and analogy. Many designs have been proposed to investigate the capabilities of this high frequency regime. In this article, the dipole-patch nanoantenna has been designed based on effective wavelength scaling and equivalent radius concept. The square cross-sectional dimension has been adapted from circular radius equivalent geometry. The concept that has been used could be a prime knowledge for designing more complex patch nanoantennas structures. In addition, the nanoantennas have a unique interest because of its capability in focusing light into a small gap region and it can be tuned at various frequency bands. Due to this, a parasitic nanoparticle is introduced at the center of the feed gap to provide a double gap region. This has enabled the field radiation to increase by approximately 22%. The enhancement factor of the field radiation will increase the efficiency of energy collector and light-emitting applications.
