Frequency reconfigurable antenna design with diode

I am looking for a skilled Freelancer to design a frequency reconfigurable antenna with a PIN diode, using Ansys (HFSS) simulation software. The project priority is to achieve maximum bandwidth, while using the same antenna structure with different frequency configurations. The antenna must be optimized to maintain maximum power efficiency within its operating range. The RF circuit design must also be carried out in Ansys (HFSS). Additionally, prototypes of the designed antenna must be built and tested for performance evaluation. Finally, all related simulation and experimental data must be documented for review. The Freelancer should have a strong background in design and simulation, particularly in the field of microwave engineering. Knowledge of antenna principles, various antenna optimization techniques, antenna theory, antenna measurements and associated equipments is a must. The ideal Freelancer would possess experience with Ansys (HFSS) software and signal-flow tunable circuits.
