Abstract

This paper presents the design and performance analysis of an optimized Super Wideband (SWB) Microstrip Patch Antenna (MPA) operating efficiently across an ultra-wide frequency range from 4 GHz to 100 GHz. The proposed antenna integrates a modified rectangular patch with a partial ground plane to enhance impedance bandwidth, gain, and radiation stability. Full-wave simulations using CST Microwave Studio (CST MWS) confirm broad impedance matching with S₁₁ < –10 dB across the entire band and a minimum return loss of –44 dB at 60.31 GHz, demonstrating excellent impedance performance. The VSWR remains below 2 throughout the operational range, verifying efficient power transfer and minimal reflection. Radiation analysis at multiple frequencies (7.76 – 98 GHz) shows stable far-field patterns with peak gains between 1.8 dB and 12.3 dB, transitioning smoothly from quasi-omnidirectional to directional radiation with increasing frequency. The optimized geometry enables continuous multimode resonance, ensuring consistent gain and impedance behavior over the full spectrum. Owing to its compact structure, high gain, and wide operating bandwidth, the proposed SWB-MPA is a strong candidate for millimeter-wave, biomedical imaging, radar, and next-generation wireless communication systems.
