Gain enhancement of SIW-integrated patch antenna for emerging millimeter wave systems

This paper presents a novel design to enhance the gain of the substrate integrated waveguide (SIW)-integrated microstrip patch antenna. An SIW air-filled cavity is created under the patch, which is excited by a narrow slot. The simulated results for reflection coefficient, gain and radiation pattern are presented. The antenna shows a 5 dB gain enhancement over the operating frequency band 54.9-64 GHz.
