Application Brief ANSYS HFSS for Antenna Simulation Antennas are virtually everywhere. From commercial applications such as smartphones, RFID tags, and wireless printers, to defense applications such as phased array antennas for aircraft radar systems or satellite-based, to provide integrated ground based communication systems. Electromagnetic simula- tion is a valuable tool in antenna design and platform integration providing the designer the ability to virtually design and evaluate what if scenarios as well as verify the fi nal manufactured design. ANSYS® HFSS™ excels at a wide variety of high frequency, full-wave, electromagnetic applications including antenna design and placement since it uses multiple advanced solver techniques to simulate not just the antenna but also the eff ects of its interaction with the entire system, including the feeding system as well as the platform. This paper describes antenna design and simulation with ANSYS HFSS, the industry leading 3D electromagnetic (EM) simulation tool for high fre- quency and high speed electronic components. Figure 1 highlights several antenna-related applications with emphasis on antennas on or around other structures. With multiple simulation technologies and powerful automated adaptive mesh refi nement
