Plasmonic metal-insulator-metal-waveguide based concurrent dual band antenna for nanoscale wireless links

Plasmonic antennas are one of the key components in the realization of future nanoscale wireless links. This paper reports design and analysis of a CPW fed dual band antenna designed using a plasmonic metal-insulator-metal waveguide operating simultaneously in O- and L-bands. The full wave simulation results obtained using CST Microwave studio shows a return loss of -18dB (VSWR of 1.11) at the desired band. The antenna has a gain of 8.88 dBi and 8.50 dBi at wavelengths 1309-nm and 1604-nm respectively. The simulated radiation pattern at desired wavelengths shows an Omni-directional pattern which is desired for wireless applications.
