Abstract :
A millimeter wave antenna is presented for 60 GHz communication using substrate integrated waveguide (SIW) technology along with dialectic resonators (DR). A very thin substrate of RT duroid 5880 having permittivity εr= 2.23, loss tangent tan δ = 0.003 is used. Same material used for the DR having thickness 0.79 mm. H-shape slot in engraved at the top ground plane that acts as a source-radiating aperture. Two pieces of DR are placed on the top metal layer of the substrate to achieve wider bandwidth. The antenna structure is modeled using CST Microwave Studio. The simulated impedance bandwidth of the antenna is 10.33 % having a gain up to 5.5 dBi. The radiation efficiency of the antenna is found to be 81 %. The results are verified by using another simulation software HFSS and found to be in good agreement.
