Abstract

In this paper, a new Leaky Wave Antenna (LWA) based on modified substrate integrated waveguide (MSIW) is proposed and investigated. It is shown that MSIW can support the Quasi-TEM mode. Leakage from the antenna is obtained by inter-digital capacitor (IDC) embedded on the top of the SIW. This antenna is simulated by HFSS and the results including radiation patterns, reflection coefficient and antenna gain is reported. The proposed antenna provides a good beam scanning in the both backward and forward radiation.
