Abstract

Microstrip patch antenna with different substrate materials which can operate in single and multiple resonating bands are useful for wireless applications. A 5CB nematic liquid crystal based microstrip antenna with dual band on a glass substrate having relative permittivity of 6.438 has been designed in this paper. Two glass substrates of 0.1mm thickness with 21x25mm2 and 19x19mm2sizes have been placed on each other, in between 0.005mm glass substrate has been placed to fill 5CB nematic liquid crystal. On the top of the substrate ‘I’ slotted rectangular patch has been placed; the dimensions of the patch have been calculated by utilizing Moth Flame Optimization (MFO) method. The proposed antenna is resonating at 1.8 GHz and 9.2 GHz frequencies with S11 as -27dB and -19.42dB, respectively. Simulated results of designed antenna with MFO algorithm are compared with Genetic Algorithm (GA).
