Frequency Recinfigurable Antenna uwb antenna Design with diodes (All the guidence Will Provided)

I am looking for a freelancer to create a frequency reconfigurable UWB antenna design using diodes and copper material. The design must have a circular geometry. Experience working with antennas and knowledge of advanced technologies in the field is required to complete this project. The antenna should be compatible with multiple protocols, and the design must provide a strong signal in different frequency bands. This project requires a creative approach to find a successful design, as the design must provide optimal performance within the available parameters.
