Substrate Integrated Waveguide Antenna With Slots For Multiband Operation Using ANN

A slotted cavity-backed Substrate Integrated Waveguide (SIW) antenna is suggested for use in wireless applications. The SIW cavity-backed antenna that is being proposed is designed for multiband operations. The operational frequencies for UMTS, WLAN, C-band and wave applications are 2.15 GHz, 2.7 GHz, 4.2 GHz, and 6.8 GHz respectively. Two typical modes are provided by a rectangular cavity (i.e., TE110 and TE120). The SIW cavity's current distribution is altered by loading slots on top of the cavity. The traditional modes couple together without enlarging the antenna and provide a new resonance frequency (i.e. Hybrid mode). As a result, the proposed antenna can operate in several bands, and the mode theory method has been used to explore radiating modes.
