Basics of a Two-Antenna System

Wireless communication systems transmit information between two antennas: a send antenna and a receive antenna. The power received by the second antenna is a product of the power sent by the first antenna; the geometry, composition, and positioning of the two antennas; the medium through which the signal travels; and the environment in which the system operates. This course will explore the basics of antenna-to-antenna communication systems, with an emphasis on understanding Frii’s Transmission equation, which is a basic formula for computing the output-to-input power ratio of a simple two-antenna system. This course was developed by Kathryn Leigh Smith, Assistant Professor in the Department of Electrical and Computer Engineering at the University of North Carolina-Charlotte, in partnership with Ansys.
