Abstract

This paper presents a slotted substrate integrated waveguide (SIW) multiple input multiple output (MIMO) antenna architecture for mm-Wave/mid-band 5G/6G satellite-cellular applications. An Expo-Gaussian statistical probability density function (PDF) has been introduced as an offset function with rotation to the radiating slots of the proposed MIMO SIW structure. To realize multidirectional multibeam MIMO antenna characteristics, both orthogonal (90°) and out-of-phase (180°) port switching technique has been established. Equivalent MIMO parameters have been realized through the S-parameters of the proposed MIMO architecture. A closed-form mathematical relationship has been established to characterize the MIMO parameters in the defined frequency band of interest. The proposed PDF rotation function enables the sidelobe level (SLL) and half-power beamwidth (HPBW) to be reduced to -20 dB and 8.5° respectively.
