Fundamental Dimension Limits of Antennas. 2004.14 pages

Ensuring Proper Antenna Dimensions in Mobile Device Designs.

"In this presentation the fundamental limits and the trade-offs between the physical size of an antenna
and its gain, efficiency and bandwidth are examined. Finally, we examine the difficulty experienced
in determining the physical dimensions of an antenna when non-antenna sections of a device’s
structure may be radiating."

CRC Press, 2004. - 472 pages. Smart antennas involve processing of signals induced on an array of sensors such as antennas, microphones, and hydrophones. They have applications in the areas of radar, sonar, medical imaging, and communications. Smart antennas have the property of spatial filtering, which makes it possible to receive energy from a particular direction while simultaneously blocking it from another direction. This property makes sma...
