Design and Analysis of Multi-Band Slotted Circular Patch Antenna for Compact UWB Applications Using HFSS Ansys

Compact multi-band antennas are essential in modern wireless communication systems where reduced size, wide operating bandwidth, and multi-frequency performance are required. This project presents the design and analysis of a multi-band slotted circular patch antenna for compact UWB applications using HFSS Ansys, with emphasis on antenna miniaturization, impedance matching, and radiation performance.

The model demonstrates how slot loading in a circular patch structure can generate multiple resonant bands and enhance bandwidth characteristics for ultra-wideband and compact wireless applications. The project is useful for research in microstrip antennas, RF and microwave engineering, multi-band wireless systems, and compact antenna optimization.
