Array of SIW resonant slot antenna for V band applications

Abstract

In this paper, the design of Substrate Integrated Waveguide (SIW) resonant slot antenna to operate in V-band applications has been realized. The basic structure of unit cell has been designed over Rogers RT/duroid 5880 dielectric substrate with dielectric constant of 2.2, loss tangent 0.0009 and with a thickness of 0.508mm. Multiple element array effects have been studied and analyzed using Ansoft HFSS full wave EM Simulator. The design has been supported with its return loss and radiation pattern characteristics to validate V-band operation. The effect of increasing the number of element in arrays has also been analyzed to improve the directivity of the system.
