E-shaped slot antenna backed with substrate integrated waveguide cavity for 60GHZ applications

Substrate integrated waveguide is good resolution for implementing for high frequency applications. In this paper, we represented SIW backed with cavity bowtie antenna which is intended by using Rogers RT/Duriod 5880 with dielectric constant 2.2. CST software is used to simulate the proposed antenna and observed the results like reflection coefficient, VSWR, gain and radiation patterns. This structure will provide 3.52 GHz impedance bandwidth with respect to −10 dB reference line, resonant frequency is 60GHz and preserves 51.14% impedance bandwidth in between 57–64 GHz.
