INOTEK 2026 COMPETITION - ULTRA WIDE BAND ANTENNA WITH METAMATRIAL-INSPIRED DEFECTED GROUND STRUCTURE FOR GAIN ENHANCEMENT

BY: MUHAMMAD ZAHID BIN MOHD NAZRI

What is this project about?
Ultra-wideband (UWB) antennas are key components in modern wireless systems such as short‑range communication, radar, and biomedical imaging, where wide impedance bandwidth and sufficiently high gain are required. Conventional UWB microstrip patch antennas on low‑cost substrates often suffer from limited gain, which reduces link reliability and restricts their use in demanding applications. This project presents the design, optimization, and experimental validation of a compact UWB microstrip patch antenna integrated with a metamaterial (MTM)‑inspired defected ground structure (DGS) to enhance gain while maintaining wideband performance.
