TECHNICAL PROGRAM:

Antenna Factor – A Deceptively Simple Parameter – Abstract:  Antennas used for EMI measurements are employed as transducers that convert field strength to antenna terminal voltage. While the concept is quite simple, the reality is that antenna factors are affected by a great many characteristics of the measurement setup, including the presence or absence of a reflective “ground” plane, the height of the antenna above the ground or chamber floor, the type of antenna, the uniformity of the field being measured, the distance between the antenna used for measurement and the source being measured, and the impedance match between the antenna and its load. This presentation will provide a basic definition of receive and transmit antenna factors, and discuss some of the setup characteristics that may affect them.

Shielding Fundamentals – Abstract:  Various approaches have been employed over time to describe electromagnetic shielding and its effectivity, but perhaps the most well known relies heavily on theoretical development by S. Schelkunoff. Developed based on impedance relationships at interfaces, observed and/or expected behavior can be described using simple equations. Related discussions focus on engineering aspects of shielding including design and magnetic effects.

Antenna Factor – A Deceptively Simple Parameter

 

Abstract:  Antennas used for EMI measurements are employed as transducers that convert field strength to antenna terminal voltage. While the concept is quite simple, the reality is that antenna factors are affected by a great many characteristics of the measurement setup, including the presence or absence of a reflective “ground” plane, the height of the antenna above the ground or chamber floor, the type of antenna, the uniformity of the field being measured, the distance between the antenna used for measurement and the source being measured, and the impedance match between the antenna and its load. Multiple authors over time have investigated this parameter and the various characteristics that affect its determination for a particular measurement. Antenna factors have been defined for both receiving and transmitting. This presentation will provide a basic definition of receive and transmit antenna factors, and discuss some of the setup characteristics that may affect them.
