Abstract

Highlights: Validation of software for high frequency and low and medium band antenna design. Electromagnetic simulation as an option to scale models for antenna design. Simulation tools properly handle any modification of the platform's structure. Suitable electromagnetic simulations result cheap, fast, versatile and accurate. Simulations aid to include electromagnetic constraints from very early design stages. Abstract: The objective pursued in this work is to highlight the convenience of using electromagnetic simulation software as an alternative to the traditional scale model measurement when dealing with the design of HF antennas on real complex platforms. The experience was developed during the building process of a real vessel. A low and a medium band antennas (fan-wire type) were designed ad-hoc for this project. The HF broadband antennas' study covered from the preliminary design stages to the final verification measurements completed onboard the ship. The experiment has demonstrated that more accurate results can be obtained when using an adequate electromagnetic simulation code, which, besides, brings important advantages in flexibility and usability. These advantages, inherent to the use of virtual models, hinge on the ability of the simulation tools to properly handle any modification of the vessel's structure that might arise during the platform construction.
