Multiband E-shape SIW antenna for mm-wave applications

摘要

This design of Antenna used for multiband Millimetre (mm) wave applications. This antenna designed using Substrate Integrated Waveguide (SIW) technology. In this design six band of frequencies are realizable for wideband. First band obtain between 38.42 GHz and 39.09 GHz with reflection coefficient of -28 dB, Second one obtain between 42.43 GHz and 43.42 GHz with reflection coefficient of -11 dB, Third one obtain between 58.55GHz and 61.12 GHz with reflection coefficient of -12.5 dB, Fourth one obtain between 72.01 GHz and 73.51 GHz with reflection coefficient of -34.5 dB, Fifth one obtain between 83.44 GHz and 84.68 GHz with reflection coefficient of -11 dB and six one obtain between 100.66 GHz and 103.23 GHz with reflection coefficient of -30 dB which all bands got good bandwidth and it is more suitable for mm wave applications.
