Antennas are the front end for every wireless communication device. They have many characteristics like gain, bandwidth, directivity, efficiency, and more. Each of these characteristics is dependent on the application. One of the most widely used techniques to enhance the antenna gain characteristic is array implementation. An antenna array can be analyzed theoretically in terms of its constituent element and array factor. The most efficient prediction of an array behavior can be achieved through simulation. This requires no prototyping or test setup, which reduces the overall design cycle time.
Ansys HFSS is an electromagnetic simulation tool based on the finite element method (FEM). In addition to design and analysis, this tool also provides many visual post-processing results for better understanding of the underlying physics.
This course demonstrates the procedure for setting up and analyzing a finite dipole array using the finite array domain decomposition method in Ansys HFSS . This course was created for Ansys Innovation Courses by Dr. Kathryn Leigh Smith, assistant professor, University of North Carolina-Charlotte, in partnership with Ansys.
