Design of Substrate Integrated Waveguide Technology Supported Dual Band MIMO Antenna

This paper introduces an outline of a Dual Band MIMO antenna for applications based on Substrate Integrated Waveguide technology (SIW). SIW has acquired a valuable and various kinds of researches, extending from microwave to optical bands due to their outstanding properties such as low costs, low losses, small footprints followed by incorporating with other types of PCBs. SIW structures can be used to prevail the above-mentioned advantages readily compared to various kinds of technologies such as co-planar waveguides, conventional waveguides, micro-strip transmission lines and so on. The indispensable cavity mode is designed on Substrate integrated waveguide to resonate at 2.4 GHz. Moreover, the 2
^nd
and 3
^rd
mode are altered and combined carefully by placing a via inside the cavity to allow the coverage of wideband in 5 GHz WLAN band.
