PPT-Antenna Theory and Matching

Farrukh Inam Applications Engineer LPRF TI 1 Agenda Antenna Basics Antenna Parameters Radio Range and Communication Link Antenna Matching Example 2 What is an Antenna Converts guided EM waves from a transmission line to spherical wave in free space or vice versa. cstcom Whitepaper CST AG 2012 Matching circuit optimization for antenna applications Impedance matching is an essential part of antenna design The input impedance of an antenna needs to be reasonably close to the amp Examples include the assignment of new doctors to hospitals students to schools and human organs for transplant to recipients Lloyd Shapley made the early theoretical contributions which were unexpectedly adopted two decades later when Alvin Roth in Individual Matching Controls are matched to cases on one or more attributes (i.e. age, gender, smoking status, etc). Each case/control pair then has identical values on the matching factors. Requi John ‘DaKahuna’ Fulmer. WT6M. Learning Objectives . Antennas - Definition. Antenna Systems. How Antennas Work.

The parameters of helical antenna are-. D- diameter of a turn on the helix antenna.. C- circumference of a turn on the helix antenna.. What is an Antenna?. An electronic device that is used either for radiating electromagnetic energy into space or for collecting electromagnetic energy for space. Any wire carrying AC current will radiate electromagnetic waves and an electromagnetic wave will induce a voltage in a length of wire. Statement of the problem.
