Abstract

This research delves into the intricate functionality of a fully planar double bow-tie antenna with orthogonal feeding and is innovatively constructed on a substrate-integrated cavity inspired by metamaterial designs. The architecture of the antenna includes Complementary Split Ring Resonators (CSRRs) and a double bow-tie patch, intricately etched onto the metal surfaces positioned on both the top and bottom of the substrate. The antenna is meticulously designed and fine-tuned for superior performance specifically in the K and Ka-band frequencies. The incorporation of the double bow-tie patch in this antenna configuration brings forth several advantageous attributes such as improved impedance matching, exceptional high gain and unidirectional radiation pattern. In a notable feature of this design, the antenna supports multiband operation which is achieved through the strategic integration of slots within the Substrate Integrated Waveguide (SIW) cavity, allowing the antenna to resonate at multiple frequencies. The antenna's superior performance and its ability to function effectively across multiple frequency bands have been rigorously validated through extensive simulation studies and thorough experimental testing.
