Triple Band Tunable SIW Cavity Antenna with Cristal Liquid Materials for Wireless Applications
This communication was developed with the purpose of presenting a frequency reconfigurable rectangular cavity backed antenna based substrate integrated waveguide, using for wireless applications. The frequency agility is obtained by the integration of a crystal liquid material between the upper face and the substrate of the proposed SIW antenna, this material maintains the proprieties of changing the permittivity and the permeability by applying a DC voltage. This is leads to the variation of the resonance frequency. Simulated results obtained by CST simulator show that the first band is tuned from 27 GHz to 28 GHz, the second one is varied from 27.85 to 29 GHz. and the frequency in the third band is changing from 29.45 GHz to 30.89 GHz. Those results are obtained when the permittivity of the CL is varying from 2.7 to 3.4. The maximum gain is around 7.92 dB and a high radiation efficiency is obtained. The proposed antenna is required for wireless applications.
