Abstract

In this paper, a new design of Substrate Integrated waveguide (SIW) horn antenna for material characterization, which works at X band is analyzed and investigated. To enhance its performance, this paper presents the interconnect SIW horn antenna for the material characterization application.  Analysis of pitch and distance on the performances of the SIW interconnect horn antenna was considered and simulated to get the best result for material characterization. The proposed antenna is in the dimension of 415 mm x 60 mm x 1.6 mm. For the simulation, antennas are numerically investigated using High Frequency Structure Simulator (HFSS) software. Performance of the modified horn is presented and compared with those of the conventional horn. Results illustrate that proposed structures of distance. From the results, proposed antenna shows good agreement with good result of pitch and distance between two horn antennas. The findings may contribute to the development of the compact design of material characterization having a comparable performance with the conventional waveguide.
