Nanoplasmonic antennas are the one of the major elements in the recognition of upcoming nanoscale wireless communication systems. In this paper, the design and analysis of two multiband antennas operating at optical bands O and L bands, using metal‐insulator‐metal (MIM) slot waveguide based step impedance resonators (SIRs) and coplanar waveguide (CPW) fed line has been investigated. The simulation results of the two antennas (A) and (B) are obtained by using full wave simulation software (CST Microwave Studio Suite) with the return loss −20 dB and −30.79 dB at desired optical bands. The antenna (A) has a gain of 8 dBi and 7.48 dBi at 1275 nm and 1616 nm wavelengths, similarly antenna (B) has a gain of 8.46 dBi and 6.23 dBi at 1294 nm and 1613 nm wavelengths. The radiation pattern of the simulated results shows the omnidirectional pattern at desired wavelengths, which is very useful for nanoscale wireless communication systems.
