Modification of a Circular Monopole Antenna UWB for the Design of a Patch Antenna Optimised Multiresonant Antenna at 2.45GHz and 5GHz

This document presents the design, simulation, and characterization of a UWB antenna, starting from a rectangular patch antenna. The initial modifications included adjustments to the ground plane and the addition of slots, yielding promising results for a UWB antenna. Advanced experiments, such as the addition of a central slot and the insertion of stubs in the patch, led to the development of a unique antenna with a bandwidth ranging from 2.89 GHz to 15 GHz. These adjustments significantly enhanced the antenna's ability to efficiently transmit signals across a wide range of frequencies, making it highly effective and versatile for various applications.
