Abstract

This paper presents a substrate-integrated waveguide (SIW) based antenna design working at a frequency of the D-band. The single-element antenna design has a matching bandwidth of 11.75% and a gain of 3.036 dBi. Antenna array configurations of 2, 4, and 8 elements are evaluated in terms of gain and bandwidth. The simulation results showed that the 2-element array configuration had a matching bandwidth of 13.41% with an antenna gain of 7.04 dBi. The 4-element array configuration had a matching bandwidth of 13.01% with an antenna gain of 9.31 dBi. Finally, the 8-element array configuration had a matching bandwidth of 13.23% with an antenna gain of 11.6 dBi. From the results obtained, increasing the number of elements of the antenna will increase the gain and bandwidth.
