Title :
A discussion on power factor, quality factor and efficiency of small antennas
Author_Institution :
MITRE Corp., Bedford
Abstract :
Here, we review these definitions and compare the actual power factors (Q´s) of fundamental antenna elements to the behavior expected from these definitions. Specifically, we examine the frequency dependence of power factor (Q) and efficiency as a function of decreasing frequency.
