Abstract :
A novel low profile circularly polarized antenna using Substrate Integrated Waveguide technology (SIW) for millimeter-wave (MMW) application is proposed. The antenna employs an X-shaped slot excited by a rectangular SIW and backed by circular cavity. The optimized design has an operating frequency range from 34.7 GHZ to 36.1 GHz with a bandwidth of 4.23%. The overall antenna realized gain is around 6.7 dB over the operating band. The simulated results using both HFSS and CSTMWS show a very good agreement between them.
