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 are dependent on the application. One of the most widely used techniques to enhance the antenna characteristics is array implementation. An antenna array consists of two or more antenna elements connected and working together, creating a resultant radiation pattern that is dependent on the spacing factor and phase difference in their excitations.
In this course, we cover the theoretical aspects of various antenna arrays. Uniform antenna arrays have identical antenna elements that are spaced equidistant from each other and excited with the same amplitude and progressive phase shift. In phased antenna arrays, the amplitude of the excitation is the same, but with a phase difference between the elements. This course uses a linear planar array to demonstrate these concepts. This course was created for Ansys Innovation Courses by Dr. Kathryn Leigh Smith, assistant professor, University of North Carolina-Charlotte, in partnership with Ansys.
