The Design of High Gain Substrate Integrated Waveguide Antennas with FR4 and RT Duroid

摘要

Background: The design and implementation of circularly polarized substrate integrated waveguide (SIW) antenna in X band using the FR4 and RT Duroid is presented in this paper. The substrate integrated waveguides represent the family of substrate integrated circuits which is planar in nature and used for the transmission of electromagnetic energy. Methods/Statistical Analysis: In this paper, the design techniques for substrate integrated waveguide using slots with the integration of microstrip with the substrates FR4 and RT Duroid are presented, which emphasize the broad perspective of the substrate integrated waveguide in circular polarization. Findings: The design has simulated in HFSS Software. From the simulation results, it is observed that gain has increased in SIW structure with slots for circular polarization as compared to SIW structure without slots also by comparing the substrate structure with RT Duroid shows good gain than the structure with FR4.
