| Abstract: | A novel wideband dual cavity backed substrate integrated waveguide antenna is presented in this paper. The properties of dual cavity backed substrate integrated waveguide (SIW), U‐iterative slot design and dumbbell shaped defected ground structure has remarkably improved the bandwidth of the proposed antenna design. The proposed antenna achieves high gain, wide bandwidth, wide beam‐width, good FBR and high radiation efficiency in a compact design. A 2 × 2 MIMO dual cavity backed SIW antenna is proposed in this research paper. The proposed antenna element achieves a bandwidth of approximately 850 MHz and a fractional bandwidth of 8.2%. The antenna achieves a peak gain of 8.99 dBi at 10.4 GHz and an average simulated radiation efficiency of 93.59% over the bandwidth. The overall size of the proposed MIMO antenna is 2.3 λg × 2.2 λg × 0.04 λg where λg is the guided wavelength at operating frequency of 10 GHz. The MIMO performance parameters are lying within acceptable limits. These performance parameters of antenna are suitable for RADAR tracking and detection application at X‐band.
