Eighth mode substrate integrated waveguide dual band resonator antennas

摘要

This study presents eighth mode substrate integrated waveguide (EMSIW)-based dual band resonator antennas with two different types of slots etched on the top patch surface. Two types of slot structures have been discussed. This antenna resonates at dual band frequencies of 2.4 and 5.8 GHz. The proposed structure has been fabricated and the simulated and measured results seem to be in good agreement. Different variations of this slot have been studied and the simulated results have been presented. The second proposed design involves a triangular complementary triangular split ring resonator slot etched on the EMSIW. This structure operates below the original cut-off frequency of the EMSIW at 1.8 GHz. The simulated and the measured results are shown to be in good agreement.
