Design & Simulation of a Printed Monopole UWB Antenna in CST -Partial ground plane & UWB performance

Описание: In this tutorial, we dive into the step-by-step process of designing a Printed Monopole Antenna optimized for Ultra-Wideband (UWB) applications (3.1 GHz – 10.6 GHz).We cover the critical physics of why a partial ground plane is used to achieve such massive bandwidth and how to optimize the gap between the patch and the ground for perfect impedance matching.

Key Learning Points:
Setting up the substrate (FR-4/Rogers) and radiating patch.
Implementing a partial ground plane for wideband performance.
Setting up the Waveguide Port and Time domain Solver.
Analyzing S-Parameters (S_{11}), VSWR, and 3D Radiation Patterns.
Surface Current distribution analysis.
