摘要：

This paper describes the design of an antenna based on Substrate Integrated Waveguide (SIW). The structure consists of slot antenna designed to operate at Ka band frequency. The effect of introducing slots and two feedline have been extensively studied. The basic structure is designed on a substrate with dielectric constant of 2.2 with a thickness of 0.508mm and loss tangent of 0.0009. The design consists of a SIW antenna fed with a normal microstrip to SIW transition. Multiple slots and different feedlines effects have been studied and analyzed using CST. Signal power reduces at mm wave frequencies as compared to lower frequency bands due to smaller effective aperture size of single element antenna. Therefore, in order to compensate these losses, the mm wave communication systems are required to have high gain antenna. A high gain and efficiency and low losses are major considerations which can be achieved by the proposed design. The proposed antenna geometry has a bandwidth of 1.27GHz with a gain of 8.9 dB at 26GHz and efficiency of 97%.
