Abstract

In this paper, a wide band tapered rod two-element MIMO antenna system is designed using a perforated H-guide section for W-band applications. The antenna system comprises of a metallic housing and a perforated H-guide section with tapered input/output dielectric sections. The dielectric section is sandwiched between the two halves of the metallic housing. The designed MIMO antenna is fed by a pair of WR-10 rectangular waveguides. The perforations in the dielectric section not only provide the mechanical stability to the structure but also facilitate high inter-port isolation. The MIMO performance of the designed antenna system is calculated with reference to envelope correlation coefficient (ECC), diversity gain (DG), and channel capacity loss (CCL). These parameters are below the satisfactory range of 0.5, 10 dB, and 0.4 bit/s/Hz. High gain (> 12 dBi), high port-to-port isolation (> 28 dB), and end-fire radiation characteristics of the designed antenna system, make it a potential candidate for W-band communication systems.
