UTILITY AND DESIGN CONSIDERATIONS OF AN ANTENNA FOR OPTICAL OFDM APPLICATIONS

Abstract

In this paper, the various favorable channel characteristics for optical OFDM have been discussed and presented .When we are using an indoor or outdoor wireless optical channel for the transmission of optical OFDM signals ,then an antenna system of 60 GHz freq. range is required. So for these particular applications of optical OFDM system a Di-pole antenna is proposed .Its design considerations and the simulated results are given in this paper. Performance of the proposed antenna is analyzed in terms of the reflection loss and its radiation pattern. Here a wireless system of super-broadband 60 GHz photonic optical OFDM system .In this paper we also used a cascaded optical RF and data modulation approach in which the advanced photonic components and a highspectral efficient QAM-OFDM modulation format is utilized. Finally we realized a compact 60 GHz photonic wireless system having a better spectral efficiency. We may also achieve very high data throughputs by making use of the 7 GHz spectral bandwidth in the 60 GHz band.
