Abstract

In this manuscript, a well-designed multiband cavity-backed X-shaped slot antenna is presented using substrate-integrated waveguide (SIW) technology. Its performance is optimized for the K and Ku bands to suit various advanced communication scenarios. Including an X-shaped slot in this design leads to significant advantages, such as better impedance matching, broadside radiation pattern, and multiband operation. In addition, it shows decent gain values of 6.89 dB at 15.02 GHz, 6.91 dB at 15.90 GHz, and 7.12 dB at frequency 19.58 GHz. This is accomplished by the innovative application of X slots on the substrate integrated waveguide (SIW) cavity. Simulated and experimental results validate multiband antenna operation and exceptional performance, highlighting its potentially high suitability for state-of-the-art millimeter-wave applications, such as satellite communications and radar systems. This compact structure, along with the proposed antenna performance metrics, confirms its feasibility for future wireless communication systems. This progress enables further developments in SIW-based antenna technology.
